This paper describes an efficient strategy to promote alkenyl thioetherifications via the Ni-catalyzed cross-coupling of inactivated or β-aryl-substituted (E)-alkenyl halides with thio-alcohols/phenols. The present strategy with easy-to-operate reaction conditions represents one of the most effective alkenyl C(sp2)–S bond-forming methods via readily accessible nickel catalysis. Notably, the mildly
本文描述了一种有效的策略,通过镍催化的失活或 β-芳基取代的 ( E )-烯基卤化物与硫醇/酚的交叉偶联来促进烯基硫醚化。本策略具有易于操作的反应条件,代表了通过易于获得的镍催化形成最有效的烯基 C(sp 2 )–S 键的方法之一。值得注意的是,所采用的温和碱性条件有助于获得广泛的范围,包括受保护的氨基酸、糖类和杂环化合物。此外,这项工作通过在几种结构复杂的天然产物和药物的后期修饰中的应用展现了其极具吸引力的实用性。

Reactions between vinyl sulfilimines and dichloroketene generated in situ from trichloroacetyl chloride in the presence of zinc-copper couple give mixtures of alpha-dichloro-gamma-butyrolactams and alpha-dichloro-gamma-butyrolactone imines. Fine-tuning of substituents within vinyl sulfilimines results in reactions with good chemoselectivity and yield for lactams.
