• Catalytic intermolecular aldol reactions of transient amide enolates in domino Michael/aldol reactions of nitroalkanes, acrylamides, and aldehydes

  Three-component reactions of nitroalkanes, acrylamides, and aldehydes by using a catalytic amount of KOH in DMSO gave β′-hydroxy-γ-nitro amides. Mechanistic studies suggested that the reactions proceeded by domino Michael/aldol reactions. The highly nucleophilic nature of transient amide enolates that were formed by Michael addition of nitronate anions to acrylamides in DMSO enabled the realization

  通过在DMSO中使用催化量的KOH，使硝基烷，丙烯酰胺和醛进行三组分反应，得到β'-羟基-γ-硝基酰胺。机理研究表明，反应是通过多米诺·迈克尔/醛醇缩合反应进行的。通过在DMSO中将亚硝酸根阴离子迈克尔加成到丙烯酰胺中而形成的瞬态酰胺烯醇盐具有高度亲核性，这使得在酸性硝基烷存在下，酰胺烯醇盐的催化分子间羟醛反应得以实现。

  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。

  A series of novel N-methyl piperidine (Nmp)-based ionic liquids with 1,2-propanediol group are synthesized and used as catalysts for both hetero-Michael addition of alpha,beta-unsaturated amides and Knoevenagel condensation at room temperature in water; and all the examined substrates could be transformed into corresponding products in good to excellent yields. Meanwhile IL-catalyzed hetero-Michael addition of alpha,beta-unsaturated amides in water has not been reported in the previous literatures. Additionally, the catalyst is recyclable for the two reactions. This finding provides a green catalyst for both hetero-Michael addition of alpha,beta-unsaturated amides and Knoevenagel condensation in water.
