α-Methoxyallyl sulfides 1 proved to serve a novel homoenolate dianion equivalent. Introduction of two electrophiles into 1 was realized by successive regiospecific reaction of an allylic moiety with electrophiles intervened by an acid-catalyzed thioallylic rearrangement. Facile desulfurization of the products under mild conditions afforded a variety of (α,β- unsaturated carbonyl compounds and 2,3,4-trisubstituted
事实证明,α-甲氧基烯丙基硫化物1具有新的均烯酸酯二价阴离子。通过将烯丙基部分与亲电子体通过酸催化的硫代烯丙基重排介入的连续的区域特异性反应来实现将两个亲电子体引入1。在温和条件下将产物容易地脱硫,得到各种(α,β-不饱和羰基化合物和2,3,4-三取代的呋喃。
