Abstract:

A general method for the formation of the cyclic ethers 9, 10, 13, 14, 16, and 28 and the lactone 30 is described. The procedure employs benzenesulfenyl chloride prepared insitu in acetonitrile and N,N-diisopropylethylamine to generate a thiiranium (episulfonium) ion intermediate from which the cyclic products arise by internal nucleophilic displacement. In the special case of the norbornene alcohols 1 and 2 the oxetanes 5 and 6 are formed by intramolecular sulfenate ester cycloaddition.

Abstract:

Leinamycin (LNM) is a potent antitumor antibiotic produced by Streptomyces atroolivaceus S-140, featuring an unusual 1,3-dioxo-1,2-dithiolane moiety that is spiro-fused to a thiazole-containing 18-membered lactam ring. Upon reductive activation in the presence of cellular thiols, LNM exerts its antitumor activity by an episulfonium ion-mediated DNA alkylation. Previously, we have cloned the lnm gene cluster from S. atroolivaceus S-140 and characterized the biosynthetic machinery responsible for the 18-membered lactam backbone and the alkyl branch at C3 of LNM. We now report the isolation and c

Abstract:

2-(Phenylthio)ethanesulfonyl chloride (1) is the major product of the reaction of (a) lithium 2-(phenylthio)ethanesulfinate (6) and chlorine, and, notwithstanding contrary reports, also of (b) benzenethiol (3) and ethenesulfonyl chloride (4), and (c) sodium 2-(phenylthio)ethanesulfonate (5) and phosphorus pentachloride. The rearrangement referred to in the title, which was proposed to account for the isolation of 2-(phenylthio)ethyl chloride (2) rather than 1 from 3 and 4, therefore does not occur. Desulfonylation of 1 to form 2, however, readily takes place thermally and, in accord with a rat

Abstract:

The cation–π interaction has been long-established to play an important role in molecular recognition, supramolecular chemistry, and molecular biology. In contrast, its potential application in small-molecule catalysis, especially as a selectivity-determining factor in asymmetric synthesis has been overlooked until very recently. This dissertation begins with an extensive literature review on the state-of-the-art research on the application of cation–π interactions in non-enzymatic catalysis of organic and organometallic transformations. The research in this field has been
