Gianneschi1, [email protected], Mollie A. Touve1, Adrian Figg1, Daniel Wright1, Chiwoo Park2, Joshua Cantlon3, Brent S. Sumerlin4. (1) Chemistry, Northwestern University, Evanston, Illinois, United States (2) Florida State University, Tallahassee, Florida, United States (3) SCIENION, San Francisco, California, United States (4) Department of Chemistry, University of Florida, Gainesville, Florida, United States We describe the development of a high-throughput, automated method for conducting TEM characterization of materials, to remove this bottleneck from the discovery process. We propose this approach will be of particular utility within the broad field of block copolymer amphiphile assembly, where researchers wish to rapidly formulate for phases of interest including vesicles in drug delivery, fragrance and cosmetic formulation. A vesicle phase is not immediately accessible, without screening block sizes and conditions, and is difficult to converge on using DLS for example, but rather often requires analysis by TEM combined with more sophisticated scattering experiments. In this presentation, we will describe the very rapid generation (hours of work as opposed to months) of phase diagrams for block copolymer amphiphiles. We demonstrate the high-throughput approach for two separate types of amphiphilic block copolymers. One type, consisting of poly(ethylene glycol)-block-poly(hydroxypropyl methacrylate), the other consisting of poly(2-(dimethylamino)ethyl methacrylate)-block- poly(hydroxypropyl methacrylate), were each prepared by systematically varying the degree of polymerization of the hydrophobic block. These were each synthesized in 96- well plates to rapidly generate a range of morphologies in aqueous solution. In this manner, 45 different assembled polymer samples were prepared at a time. These samples were sampled by automated picoliter volume liquid handling (piezoelectric robotic dispenser) and analyzed by automated transmission electron microscopy (TEM by SerialEM) and automated image analysis to rapidly generate phase diagrams. Moreover, we will describe approaches for conducting polymerization and assembly of nanomaterials in situ, in a liquid TEM cell. Linking the process of reaction development and discovery directly to the process of imaging materials. POLY 2: Accelerated polymerization-induced self-assembly using automated continuous-flow reactors Nicholas Warren, [email protected]. University of Leeds, Leeds, United Kingdom Continuous-flow synthesis is becoming one of the key technologies for sustainable and reproducible manufacture of advanced chemical products. For polymer syntheses, it offers numerous potential advantages with respect to precision control, safety, reduced energy usage and facile scale up. The implementation of continuous-flow reactor platforms for RAFT polymerization is currently being reported by several significant research groups, who have demonstrated excellent control and the ability to produce well-defined polymers and polymer nanoparticles. Alongside the developments in continuous manufacturing processes are those in RAFT polymerization technology itself. including polymerization-induced self-assembly (PISA) and Ultrafast (UF) RAFT polymerisation. PISA enables the in-situ formation of block copolymer nanoparticles while UF RAFT reduces reaction times from hours down to minutes. Herein, we demonstrate that by combining continuous-flow platforms with the latest advances in RAFT polymerization, it is possible to accelerate the synthesis of diblock copolymer nanoparticles via aqueous dispersion polymerization. By judiciously selecting fast propagating monomers and initiators which have very short half-lives at elevated temperatures, diblock copolymer nanoparticles can be produced in under 20 minutes. Moreover, by automating the reactors, the operator merely needs to prepare the primary solutions, program the pumps and collect the sample. This method has important implications with respect to efficient, highly reproducible, multi-scale manufacture, particularly as automation enables the development of artificially intelligent reactor systems. POLY 3: How do diblock copolymer micelles form during polymerization-induced self-assembly? Matthew J. Derry, [email protected], Oleksandr Mykhaylyk, Anthony J. Ryan, Steven P. Armes. Department of Chemistry, University of Sheffield, Sheffield, United Kingdom Reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of a range of vinyl monomers enables the convenient synthesis of diblock copolymer spheres, worms or vesicles in various solvents. Such formulations are an example of polymerization-induced self-assembly (PISA). Chain extension of a soluble stabilizer block with a suitable monomer initially produces soluble diblock copolymer chains. Micellar self-assembly occurs at some critical degree of polymerization (DP) for the growing insoluble block. After this nucleation event, sterically-stabilized nanoparticles grow in size. Depending on the precise PISA formulation, various morphological transitions can be observed by time-resolved small-angle X-ray scattering (SAXS). In the present work, poly(stearyl methacrylate)-poly(benzyl methacrylate) (PSMA31- PBzMA2000) spheres are targeted in mineral oil. Remarkably, the nascent particles that are formed during micellar nucleation are non-spherical (see Figure 1). Systematic variation of this PISA formulation indicated that such anisotropic aggregates are only formed when the monomer concentration is sufficiently high (i.e. when a relatively high insoluble block DP is targeted). Figure 1. SAXS patterns recorded for PSMA31-PBzMA2000 spheres in mineral oil (left), corresponding pair-distance distribution functions (PDDFs) obtained by indirect Fourier transformation of the experimental SAXS patterns (centre) and ab initio low resolution structure of the scattering objects derived from these SAXS data (right). POLY 4: RAFT dispersion polymerization in silicone oil Matthew J. Rymaruk1,2, [email protected], Saul J. Hunter4, Cate O'brien2, Steven Brown3, Clive Williams3, Steven P. Armes2. (1) Chemistry, University of Sheffield, Beverley, United Kingdom (2) Univ of Sheffield Dept of Chem, Sheffield, United Kingdom (3) Scott Bader Company Ltd, Northamptonshire, United Kingdom (4) University of Sheffield, Sheffield, United Kingdom We describe the synthesis of diblock copolymer nanoparticles in low-viscosity silicone oils. More specifically, a near-monodisperse monohydroxy-terminated polydimethylsiloxane was esterified using a carboxylic acid-functionalized trithiocarbonate to yield a PDMS66 precursor with a mean degree of functionality of 92 %. This PDMS66 precursor was then chain-extended in turn using nine different methacrylic monomers in a low-viscosity silicone oil (decamethylcyclopentasiloxane). In each case the target DP of the core-forming block was fixed at 200 and the copolymer concentration was 25 % w/w. Transmission electron microscopy studies indicated that kinetically-trapped spheres were obtained in almost all cases. The only exception was 2-(dimethylamino)ethyl methacrylate (DMA), which enabled access to spheres, worm or vesicles. This striking difference is attributed to the relatively low glass transition temperature for this latter block. A phase diagram was constructed for a series of PDMS66-PDMAx nano-objects by systematically increasing the PDMA target DP from 20 to 220 and varying the copolymer concentration between 10 and 30 % w/w. Higher copolymer concentrations were required to access a pure worm phase, whereas only spheres, vesicles or mixed phases were accessible at lower copolymer concentrations. Gel permeation chromatography studies indicated a linear evolution of number-average molecular weight with PDMA DP while dispersities remained below 1.39, suggesting relatively well-controlled RAFT polymerizations. Small angle x-ray scattering was used to characterize selected examples of spheres, worms and vesicles. Finally, PDMS66- PDMAx worms were also prepared in n-dodecane, hexamethyldisiloxane

Abstract A series of sulfonyl-containing 5-fluoro-2´-deoxyuridine (FdU) phosphotriester and phosphoramidate analogues were designed and synthesized as anticancer prodrugs of FdUMP. Stability studies have demonstrated that these compounds underwent pH dependent β-elimination to liberate the corresponding nucleotide species with half-lives in the range of 0.33 to 12.23 h under model physiological conditions in 0.1M phosphate buffer at pH 7.4 and 37 °C. Acceleration of the elimination was observed in the presence of human plasma. Compounds with FdUMP moiety (4-9) were considerably more potent than those without (1-3) as well as 5-fluorouracil (5-FU) against Chinese hamster lung fibroblasts (V-79 cells) in vitro. Addition of thymidine (10 µM) reversed the growth inhibition activities of only 5-FU and the compounds with FdUMP moiety, but had no effect on those without. These results suggested a mechanism of action of the prodrugs involving the intracellular release of FdUMP. Introduction 5-Fluoro-2´-deoxyuridine-5´-monophosphate (FdUMP) is the major metabolite responsible for the anticancer activity of 5-FU (Chart 1).

  • William S. Johnson
    William S. Johnson February 24, 1913 - August 19, 1995 William S, Johnson was a highly respected leader among research chemists and educators while, at the same time, he was humble about his accomplishments. His career spanned an explosive period of rapid progress in science and he was at the cutting edge of many of the basic changes that have taken place. His deep respect and love for science led to a career that was characterized by creative, insightful and thorough research and resulted in a body of work on steroid synthesis that is unparalleled for its thorough comprehensive coverage. Bill Johnson did his undergraduate studies at Amherst College, an institution that has spawned a number of chemical leaders. After finishing his doctoral work with Professor Louis Fieser at Harvard University in late 1939 and a brief postdoctoral stint at Harvard with Professor R.P. Linstead, Johnson began his independent academic career at the University of Wisconsin in 1940. The research program that Johnson initiated was directed at the development of methodology for the synthesis of steroids. While the approaches would change over the years, this theme would become the dominant direction for Bill Johnson's research effort over his entire academic career. The "Wisconsin era" was devoted to a classical approach to the total synthesis of the steroid skeleton and resulted in the development of the benzylidene blocking group for the angular methylation of a-decalone type molecules, the use of the Stobbe reaction for the synthesis of the aromatic steroids equilenin and estrone, and the "hydrochrysene approach" to the total synthesis of nonaromatic steroids.

Murtadha All rights reserved 2020 iii ABSTRACT ASYMMETRIC SYNTHESIS OF ORGANOPHOSPHATES AND THEIR DERIVATIVES Name: Murtadha, Batool J. University of Dayton Advisor: Dr. Jeremy Erb Organophosphorus compounds (OPs) are widely used in the agricultural industry especially in the pesticide market. Phosphates play a huge role as biological compounds in the form of energy carrier compounds like ATP, and medicine as antivirals. OPs have become increasingly important as evidenced by the publication of new methods devoted to their uses and synthesis. These well-established studies lay the basis for industrial organic derivatives of phosphorus preparations. The current work explored methods of synthesizing chiral organophosphate triesters. We experimented with different processes roughly divided into either an electrophilic or nucleophilic strategy using chiral Lewis acids, organocatalysts (HyperBTM), activating agents, and chiral auxiliaries with the goal of control stereoselectivity. These methods were explored through the use of different starting materials like POCl3, triethyl phosphate, methyl phosphordichloradate, and PSCl3.

    1 HIST’S SIXTY YEARS OF SPONSORED PUBLICATIONS: AN EXPANDED 2 BIBLIOGRAPHY 3 Mary Virginia Orna ([email protected]) 4 5 INTRODUCTION 6 For sixty years, the Division of the History of Chemistry (HIST) has sponsored publications 7 of history-related volumes drawn for the most part from symposia that were presented at 8 American Chemical Society (ACS) meetings. The origin of each volume depended upon 9 individuals who organized symposia, or in some cases, proposed book volumes. It has been 10 the practice of the Division to provide some financial support for these ventures; many 11 organizers were able to obtain additional support from various types of grants and 12 contributions. Generally, the editor of the volume was also the organizer of the event. Except 13 for the Archaeological Chemistry volumes, there were no set series or themes over the years, 14 but the volumes naturally fell into the six categories given in the Outline and Overview of 15 this article. 16 Since this paper has as its goal a permanent record of this HIST-initiated activity, 17 each volume will be highlighted with a re-publication of parts of its Preface and if warranted, 18 some additional information on the contents of the volume. Since a large percentage of the 19 volumes’ contents (titles and abstracts of papers) can be found on the ACS website, 20 [www.acs.org/publications], they will not be repeated here but a link to the volume on the 21 ACS website will be provided. However, several volumes were published elsewhere, and 22 even some volumes published by the ACS have no presence on its website.
