  Abstract Lithium tetrafluoroborate has been demonstrated for the first time to be an efficient catalyst in intermolecular aza-Michael addition aromatic amines to electron deficient alkenes. Suitability of the same catalyst in intramolecular aza-Michael addition leading 2-aryl-2,3-dihydroquinolin-4(1H) ones has also been described.

  A task-specific basic ionic liquid, [Bmim]OH, has been introduced as a catalyst for the aza-Michael addition of aromatic amines and N-heterocycles to cyclic or acyclic ketones under neat conditions. The catalyst can be recycled for subsequent reactions without any appreciable loss of efficiency.

  已引入一种特定任务的碱性离子液体[Bmim] OH，作为在纯净条件下将芳族胺和N-杂环向氮杂-迈克尔加成至环状或无环酮的催化剂。催化剂可以再循环用于随后的反应，而没有任何明显的效率损失。

  Glycerol was used as a reaction medium as well as promoter for aza-Michael addition of aromatic amines to electronic deficient α,β-unsaturated ketones. Various aromatic amines can react smoothly with chalcone, 2-cyclohexen-1-one, 2-cyclopenten-1-one, and ethyl vinyl ketone to achieve good to excellent yields in the absence of any catalyst.

  甘油被用作反应介质，同时也是芳香胺与缺电子的α,β-不饱和酮的aza-Michael加成反应的促进剂。多种芳香胺能够顺利地与查尔酮、2-环己烯-1-酮、2-环戊烯-1-酮和乙基乙烯酮反应，在无需任何催化剂的情况下实现优良至极佳的产率。

  The aza-Michael addition of aromatic amines to alpha,beta-unsaturated ketones was carried out effectively at room temperature in good to excellent yields without any catalyst or solvent. It was significant that part of adducts could be collected in almost quantitative yield without column chromatography. This procedure offered a green, efficient, and practical approach for the synthesis of beta-amino ketones. (C) 2011 Elsevier Ltd. All rights reserved.
