A two step procedure for the conversion of α-oxoketene dithioacetals to β-substituted α, β-unsaturated thioesters or acids is described. The overall transformation represents a 1,3-carbonyl transposition in which the original ketone carbonyl emerges as the carbonyl of an acid or thioester. The resulting thioesters and acids constitute versatile acylating reagents in accord with established procedures
描述了将α-氧杂环丁烯二硫缩醛转化为β-取代的α,β-不饱和硫代酯或酸的两步程序。整体转化代表1,3-羰基转座,其中原始的羰基酮以酸或硫代酯的羰基形式出现。根据确定的程序,所得的硫酯和酸构成通用的酰化试剂。
