developed. This methodology involves the in situ generation of thiolate anions by nucleophilic substitution between potassium thioacetate and alkyl halides followed by fragmentation. Further reactions of these thiolate anions with substituted (E,Z)-β-styryl halides gave the corresponding sulfides with retention of stereochemistry in good to excellent yields. This procedure does not require a metal catalyst
开发了一种新的苯乙烯基烷基硫化物一锅合成方案。该方法涉及通过硫代乙酸钾和烷基卤化物之间的亲核取代,然后进行碎裂,原位生成硫醇盐阴离子。这些硫醇盐阴离子与取代的 (E,Z)-β-苯乙烯基卤化物的进一步反应得到相应的硫化物,并以良好至极好的产率保留立体化学。该过程不需要金属催化剂,它在温和的条件下和短时间内进行,并且它没有恶臭和对空气敏感的烷基硫醇。
