well. The present methodology appears to be better than the other catalyzed transamidations reported recently. A simple protocol, which is catalyst-free, metal-free, and chemoselective, for transamidation of activated secondary amides in ethanol as solvent under mild conditions is reported. A wide range of amines, amino acids, amino alcohols, and the substituents, which are problematic in catalyzed transamidation
摘要 据报道,在温和条件下,无溶剂,无金属和化学选择性的简单方案可用于乙醇中作为溶剂的活化仲酰胺的氨基转移。在该方法学中容许在催化的转酰胺基化中有问题的各种各样的胺,氨基酸,氨基醇和取代基。转酰胺基反应也成功地扩展到水作为介质。本方法学似乎比最近报道的其他催化的转酰胺作用更好。 据报道,在温和条件下,无溶剂,无金属和化学选择性的简单方案可用于乙醇中作为溶剂的活化仲酰胺的氨基转移。在该方法学中容许在催化的转酰胺基化中有问题的各种各样的胺,氨基酸,氨基醇和取代基。转酰胺基反应也成功地扩展到水作为介质。本方法学似乎比最近报道的其他催化的转酰胺作用更好。
