A simple and practical thio-Michael addition of α,β-unsaturated amides catalyzed by Nmm-based ionic liquids with a 1,2-propanediol group has been developed. All the α,β-unsaturated amides without substituents at the carbon end could smoothly react with sulfur-nucleophiles in water. Meanwhile for thio-Michael addition of α,β-unsaturated amides with substituents at the carbon end, the relevant product
已经开发了一种简单实用的由带有1,2-丙二醇基团的Nmm基离子液体催化的α,β-不饱和酰胺硫代-迈克尔加成反应。所有在碳末端没有取代基的α,β-不饱和酰胺都可以与水中的亲硫试剂顺利反应。同时,对于在碳末端带有取代基的α,β-不饱和酰胺的硫代-迈克尔加成反应,也可在无溶剂条件下于55°C成功获得相关产物。此外,IL催化剂是可回收的并且可用于克级合成。
