Abstract Different thiols were successfully reacted with benzyl allenoate resulting in E-selective thia-Michael addition product with α,β-unsaturation as confirmed by single crystal x-ray crystallographic analysis. The thia-Michael addition is chemoselective and free amine and alcohol groups were well tolerated. Catalytic triethylamine was required for high conversion. Fair to excellent yields were obtained for a variety of aliphatic, aryl and heteroaryl thiols. Graphical Abstract

E-和化学选择性硫杂-迈克尔加成到苯丙酸苄酯

摘要 不同的硫醇与烯丙酸苄酯成功反应，产生了具有 α,β-不饱和度的 E 选择性硫杂-迈克尔加成产物，单晶 X 射线晶体学分析证实了这一点。硫杂-迈克尔加成是化学选择性的，并且游离胺和醇基团耐受性良好。高转化率需要催化三乙胺。各种脂肪族、芳基和杂芳基硫醇获得了相当到极好的收率。图形概要
