Polycyclic Aromatic Hydrocarbon Structure Index
NIST Special Publication 922 Polycyclic Aromatic Hydrocarbon Structure Index Lane C. Sander and Stephen A. Wise Chemical Science and Technology Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899-0001 December 1997 revised August 2020 U.S. Department of Commerce William M.

Kammer, Director Polycyclic Aromatic Hydrocarbon Structure Index Lane C. Sander and Stephen A. Wise Chemical Science and Technology Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 This tabulation is presented as an aid in the identification of the chemical structures of polycyclic aromatic hydrocarbons (PAHs). The Structure Index consists of two parts: (1) a cross index of named PAHs listed in alphabetical order, and (2) chemical structures including ring numbering, name(s), Chemical Abstract Service (CAS) Registry numbers, chemical formulas, molecular weights, and length-to-breadth ratios (L/B) and shape descriptors of PAHs listed in order of increasing molecular weight. Where possible, synonyms (including those employing alternate and/or obsolete naming conventions) have been included. Synonyms used in the Structure Index were compiled from a variety of sources including “Polynuclear Aromatic Hydrocarbons Nomenclature Guide,” by Loening, et al. [1], “Analytical Chemistry of Polycyclic Aromatic Compounds,” by Lee et al. [2], “Calculated Molecular Properties of Polycyclic Aromatic Hydrocarbons,” by Hites and Simonsick [3], “Handbook of Polycyclic Hydrocarbons,” by J. R. Dias [4], “The Ring Index,” by Patterson and Capell [5], “CAS 12th Collective Index,” [6] and “Aldrich Structure Index” [7]. In this publication the IUPAC preferred name is shown in large or bold type. -

Tri- and tetrasubstituted carbocyclic and heterocyclic alkenes may be formed by this method, and the products obtained may serve as useful intermediates for natural product synthesis. Alkoxycycloalkene carboxylates are highly useful trialkyl phosphonacetate.5 Since the efficiency of this proto- starting materials for organic synthesis (Figure 1). col is often low, the development of an alternative method for Stereoselective introduction of carbon substituents the preparation of cycloalkenol carboxylates of varying ring β to the ester functional group may be accomplished sizes would clearly be of value for natural product synthesis. by allylic substitution or Michael addition reactions, Here we report our efforts toward the realization of this goal as shown by Villieras et al.1 Ogasawara has prepared and detail a novel Lewis acid catalyzed condensation of ynol the nitraria alkaloids (þ)-nitramine, (þ)-isonitramine, and ether-acetals -

Recent Studies on the Aromaticity and Antiaromaticity of Planar Cyclooctatetraene

Received: 29 December 2009; in revised form: 23 January 2010 / Accepted: 4 February 2010 / Published: 5 February 2010 Abstract: Cyclooctatetraene (COT), the first 4n π-electron system to be studied, adopts an inherently nonplanar tub-shaped geometry of D2d symmetry with alternating single and double bonds, and hence behaves as a nonaromatic polyene rather than an antiaromatic compound. Recently, however, considerable 8 π-antiaromatic paratropicity has been shown to be generated in planar COT rings even with the bond alternated D4h structure. In this review, we highlight recent theoretical and experimental studies on the antiaromaticity of hypothetical and actual planar COT. In addition, theoretically predicted triplet aromaticity and stacked aromaticity of planar COT are also briefly described. Keywords: antiaromaticity; cyclooctatetraene; NMR chemical shifts; quantum chemical calculations; ring current 1. Introduction Cyclooctatetraene (COT) was first prepared by Willstätter in 1911 [1,2]. At that time, the special stability of benzene was elusive and it was of interest to learn the reactivity of COT as the next higher vinylogue of benzene. However, unlike benzene, COT was found to be highly reactive to electrophiles just like other alkenes. -

A Single-Flask Synthesis of α-Alkylidene and α-Benzylidene Lactones from Ethoxyacetylene, Epoxides/Oxetanes, and Carbonyl Compounds Kevin Nga, Vincent Trana, and Thomas Minehana,* aDepartment of Chemistry and Biochemistry, California State University, Northridge, 18111 Nordhoff Street, Northridge, CA 91330, USA Abstract Low temperature treatment of (ethoxyethynyl)lithium with epoxides or oxetanes in the presence of BF3•OEt2, followed by addition of aldehydes or ketones and warming to room temperature, affords structurally diverse five- and six-membered α-alkylidene and α-benzylidene lactones (5) in good to excellent yields. This one-pot process, in which three new carbon-carbon bonds and a ring are formed, affords substituted α,β-unsaturated lactones of predominantly Z-configuration. The reaction likely occurs via alkyne-carbonyl metathesis of a hydroxy-ynol ether intermediate, acid-promoted alkene E- to Z-isomerization, and lactonization.

In fact, all of the cyclophanes have an IC50 between 0.5–5.0 mg/mL but they are not selective for human solid tumor cell lines in the Corbett assay.2 The structurally similar chlorinated nostocyclophanes3 were found to be the major cytotoxic component of Nostoclickia (Fig. 1). 1 Moore, B.

Coles-Taylor Title: Controlling Transition Metal-Catalyzed Alkyne Annulations Utilizing Polarized Ynol Ethers Advisor: Brian Michel, PhD Degree Date: June 2020 Abstract Transition metal-catalyzed alkyne annulations have developed into incredibly powerful synthetic tools over there the past quarter century. These reactions provide rapid access to important organic scaffolds such as indole, quinoline, isoquinoline, indene, and isocoumarin scaffolds. Transition metal mediated alkyne annulations have proven invaluable in synthetic fields, such as natural product total synthesis, by offering efficient pathways to otherwise synthetically difficult to access substrates. Foundational works performed by chemist such as Larock, Ackermann, Satoh, and Miura have been established through relying upon the usage of symmetrical alkynes. When unsymmetrical alkynes are used in annulation processes mixtures of regioisomers are often isolated. While methodologies have been developed which regioselectively deliver annulation products, the regioselective nature of these reactions is often empirically determined and obtained with little synthetic design to impact the alkyne migratory insertion step of the catalytic cycle. -
