  Green, efficient and practical Michael addition of arylamines to α,β-unsaturated ketones

  摘要：

  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.

  日期：——

  An efficient and “green” protocol for the synthesis of 3-acylimidazo[1,2-a]pyridines through intramolecular oxidative α-amination of carbonyl compounds has been developed. The reaction proceeds smoothly utilizing I2 as a catalyst and H2O2 as an oxidant under neat condition with broad substrate scope. Several complex nitrogen-containing fused rings are conveniently constructed, which are not easy to
