Unusual addition reactions of alkoxymethyl substituted allylstannanes to a carbonyl compound. Complete product control by the alkoxy group regardless of original regio- and stereo-chemistry

Abstract

Alkoxymethyl substituted allylstannanes have been prepared and their Lewis acid mediated allylation of a carbonyl compound results in the formation of the corresponding cis-4-alkoxymethylbut-3-en-1-ol regardless of the regio- and stereo-chemistry of the original allylstannanes.
