  Synthesis of bischromones by deformylative Mannich type reaction on chromone-3-carbaldehyde using α-aminoacid as the source of amine

  摘要：

  Chromone-3-carbaldehyde reacts with N-methylglycine or glycine in the presence of excess formaldehyde to produce N-(chromone-3-ylmethyl)-N-methylglycine or N,N-di(chromone-3-ylmethyl)glycine, respectively, by a deformylative Mannich type reaction. Use of alanine or leucine or methionine in place of glycine produces N-(chromone-3-ylmethyl)alanine/-leucine/-methionine, respectively. (C) 2009 Elsevier Ltd. All rights reserved.
