摘要

A new highly stereoselective and regiospecific general method for the conversion of active methylene ketones to &unsaturated 0-methyl esters, S-methyl esters, and aldehydes via the corresponding oxoketene dithioacetals has been developed. Thus the [bis (methylthio) methylene] carbinols 7a-g obtained by sodium borohydride reduction of the corresponding oxoketene dithioacetals 6a-g, derived from acetophenones and their higher homologues, ...
