Polyfunctional adducts assembled with the help of a one-pot sequence of three AdE reactions as synthetically useful intermediates. The course of the Lewis acid induced transformations of the 4,6-dialkoxy-7-arylthioheptene moiety
摘要:
Data on the selectivity of the Lewis acid induced transformations of the title adducts are presented and the routes leading to formation of products containing either cyclohexane or 1,3-dienes units are described. (C) 2001 Elsevier Science Ltd. All rights reserved.
Structure and reactivity of thiophanium salts, the elusive intermediates in ArS+-mediated one-pot sequence of three AdE reactions
摘要:
The structure of the previously postulated cationoid intermediate, presumably formed in ArS+-mediated coupling of two vinyl ether units, was firmly established as (1R*,2R*,4S*)-2,4-dimethoxy-3,3-dimethyl-1-p-tolylthiophanium salt and its reactivity was elucidated (C) 1998 Elsevier Science Ltd.

A new method is proposed for the controlled synthesis of polyfunctional compounds with formation of two new carbon-carbon bonds; the method is based on the following reaction sequence, which can be carried out in a single flask: addition of ArSCl to vinyl ether I, reaction of the resultant adduct with vinyl ether II in the presence of Lewis acid to form a cationic complex, and treatment of the latter with allyl derivatives of boron or magnesium.
