Synthetic Routes to Bromo-Terminated Phosphonate Films and Alkynyl Pyridine Compounds for Click Coupling Poornima Rachel Sunder Thesis submitted to the faculty of University of Mary Washington in partial fulfillment of the requirements for graduation with Honors in Chemistry (2018) ABSTRACT Click reactions are a highly versatile class of reactions that produce a diverse range of products. Copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions require an azide and a terminal alkyne and produce a coupled product that is “clicked” through a triazole ring that can have a variety of substituents. In this work, bromo-terminated phosphonate films on copper oxide surfaces were explored as the platform for click coupling, as the terminal azide needed for the reaction can be generated through an in situ SN2 reaction with a terminal bromo group. The reactions were characterized using model reactions in solution before being conducted on modified copper oxide surfaces.

  • When Phosphosugars Meet Gold: Synthesis and Catalytic Activities of Phostones and Polyhydroxylated Phosphonite Au(I) Complexes
    Article When Phosphosugars Meet Gold: Synthesis and Catalytic Activities of Phostones and Polyhydroxylated Phosphonite Au(I) Complexes Gaëlle Malik, Angélique Ferry and Xavier Guinchard * Received: 23 September 2015 ; Accepted: 20 November 2015 ; Published: 27 November 2015 Academic Editor: Bimal Banik Institut de Chimie des Substances Naturelles, CNRS UPR 2301, Université Paris-Sud, Université Paris-Saclay, 1 Avenue de la Terrasse, 91198 Gif sur Yvette cedex, France; [email protected] (G.M.); [email protected] (A.F.) * Correspondence: [email protected]; Tel.: +33-1-69-82-30-66 Abstract: The synthesis and characterization of P-chiral phosphonite-, phosphonate- and thiophosphonate-Au(I) complexes are reported. These novel ligands for Au(I) are based on glycomimetic phosphorus scaffolds, obtained from the chiral pool. The catalytic activities of these complexes are shown in the cyclization of allenols and the hydroamination of 2-(2-propynyl)aniline combined with an organocatalyzed reduction to the corresponding 2-phenyl tetrahydroquinoline. All described gold complexes present excellent catalytic activities. Keywords: gold catalysis; phosphosugars; catalysis; heterocycles; P-stereogeny 1. Introduction One of the major advances of the 21th century in organic chemistry is undoubtedly the increased importance of gold catalysis. Long believed to be useless for catalysis, gold complexes have emerged as powerful tools for the catalysis of myriads of reactions [1–9]. In particular, the gold tolerance towards air, moisture and numerous chemical functionalities renders the use of these catalysts very convenient. However, the bicoordinate linear geometry of gold(I) complexes makes the control of the asymmetry difficult, the chiral ligand being placed in a distal position to the reactive cationic center.

Yoke r The ligands in the series EtnP(OEt)3_11, n = 0 - 3,all form pseudotetrahedral high-spin bis -complexes with cobalt (II) chloride. Magnetic, spectrophotometric, conductivity, and molecular weight data show that the phosphorus ester ligands (but not the phosphine) also form five-coordinate low-spin tris-complexes; these can be isolated with the phosphonite and phosphinite ligands, while the existence of the tris -phosphite is marginal.At cobalt (II) to phosphorus ester mole ratios of 1:2, a mixture of species is present in all cases.All are non-conducting in nitrobenzene. The ester complexes are much more susceptible to autoxidation than is the phosphine complex.

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.

  • Applications of Boronic Acids in Organic Synthesis
    Applications of Boronic Acids in Organic Synthesis A dissertation presented by Pavel Starkov in partial fulfilment of the requirements for the award of the degree of DOCTOR OF PHILOSOPHY at UNIVERSITY COLLEGE LONDON Department of Chemistry Christopher Ingold Laboratories University College London 20 Gordon Street WC1H 0AJ London Declaration This dissertation is the result of my own work. Where information has been derived from other sources it has been clearly indicated so and acknowledged accordingly. /Pavel Starkov/ ii Abstract This thesis describes progress on the application of boronic acids and borate esters as catalysts and reagents in synthetic organic synthesis, focusing on two areas: one-pot enolate formation/aldol reactions and amide bond formation. Chapter 1 introduces the reader to boronic acids and derivatives thereof, their methods of preparation and their use in synthetic organic chemistry as reactants, reagents and catalysts. Chapter 2 covers current chemical methods and cellular alternatives for amide bond formation. Here, we also discuss our use of boron reagents for the activation of carboxylic acids as well as amides. Chapter 3 introduces a new concept in catalytic aldol reactions, i.e. an alternative strategy to access boron enolates in situ. The work covers successful demonstration of the feasibility of such an approach on an intramolecular system. A novel variation of aerobic Chan–Evans– Lam coupling, an intramolecular coupling of an aliphatic alcohol with a boronic acid using catalytic copper, is also introduced Chapter 4 builds on our observations on gold catalysis and especially that in relation to electrophilic halogenations. Chapter 5 contains full details of the experimental procedures.

Keywords: H-phosphonates; phosphate analogs; biological activity; nucleic acids; drugs. INTRODUCTION Located at the crossroad of various bioinformation exchange pathways, phosphorus-containing com- pounds play a key role in living organisms as carriers of genetic information and important signalling, regulatory, energy transfer, and structural compounds [1]. Due to this pivotal role, biologically impor- tant phosphorus compounds have become therapeutic targets in various modern medicinal techniques, such as antisense [2] and antigene [3] approaches to modulation gene expression, or a gene silencing technique using short interfering RNA (siRNA) [4]. To maximize the desired biological effect and to minimize cytotoxicity, a biologically active com- pound has to have very precisely adjusted chemical and pharmacokinetic properties. This can be achieved by, e.g., changing pKa values of the ionizeable functions, changing electronegativity of the substituents, their size, hydrophobicity, etc. These features can also influence transport of a drug across cell membranes, its preferential degradation in normal or activation in the neoplastic or virus-infected cells, and can contribute to the overall efficiency of the drug. A prominent example here are antiviral pronucleotides in which the phosphate moiety is masked with alkyl or aryl groups that are removed chemically and enzymatically in cells to produce an active antiviral nucleotide [5].

  • The Hydrolysis of Phosphinates and Phosphonates: a Review
    molecules Review The Hydrolysis of Phosphinates and Phosphonates: A Review Nikoletta Harsági and György Keglevich * Department of Organic Chemistry and Technology, Budapest University of Technology and Economics, 1521 Budapest, Hungary; [email protected] * Correspondence: [email protected]; Tel.: +36-1-463-1111 (ext. 5883) Abstract: Phosphinic and phosphonic acids are useful intermediates and biologically active com- pounds which may be prepared from their esters, phosphinates and phosphonates, respectively, by hydrolysis or dealkylation. The hydrolysis may take place both under acidic and basic conditions, but the C-O bond may also be cleaved by trimethylsilyl halides. The hydrolysis of P-esters is a challenging task because, in most cases, the optimized reaction conditions have not yet been explored. Despite the importance of the hydrolysis of P-esters, this field has not yet been fully surveyed. In order to fill this gap, examples of acidic and alkaline hydrolysis, as well as the dealkylation of phosphinates and phosphonates, are summarized in this review. Keywords: hydrolysis; dealkylation; phosphinates; phosphonates; P-acids 1. Introduction Phosphinic and phosphonic acids are of great importance due to their biological activity (Figure1)[ 1].

Received: 13 May 2017; Accepted: 4 July 2017; Published: 11 July 2017 Abstract: Organophosphorus compounds containing P-C bonds are increasingly developed as flame retardant additives due to their excellent thermal and hydrolytic stability and ease of synthesis. The latest development (since 2010) in organophosphorus flame retardants containing P-C bonds summarized in this review. In this review, we have broadly classified such phosphorus compounds based on the carbon unit linked to the phosphorus atom i.e., could be a part of either an aliphatic or an aromatic unit. We have only considered those published literature where a P-C bond was created as a part of synthetic strategy to make either an intermediate or a final organophosphorus compound with an aim to use it as a flame retardant. General synthetic strategies to create P-C bonds are briefly discussed. Most popular synthetic strategies used for developing P-C containing phosphorus based flame retardants include Michael addition, Michaelis–Arbuzov, Friedels–Crafts and Grignard reactions.
