Abstract

Abstract: Stereochemical aspects of the intramolecular Diels-Alder reactions of a series of deca-2, 7, 9-trienoate esters are described. The thermal cyclizations of trienes 4-8 afforded mixtures of cycloadducts, among which the trans-fused products predominated. The product selectivity in these cases was independent of dienophile stereochemistry. The structures of the cycloadducts were established by chemical methods, including product ...
