A stereoselective one-pot procedure was developed to prepare S-substituted (Z)-enol esters through a base-triggered rearrangement. This transition metal-free multicomponent approach can be performed under an air atmosphere at room temperature, tolerates a wide set of chemical functionalities and generally affords high isolated yields. The (Z)-selectivity arises from the [1,4]-S- to O-acyl migration
开发了立体选择性一锅法程序以通过碱触发的重排制备S-取代的(Z)-烯醇酯。这种无过渡
金属的多组分方法可在室温下的空气气氛下进行,可耐受多种
化学官能团,并且通常可提供较高的分离收率。(Z)-选择性源自[1,4] -S-向O-酰基的迁移。
