Polyfunctional adducts assembled with the help of a one-pot sequence of three Ad_E 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 teh 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.
