A microwave-assisted, highly chemoselective protocol has been developed for the transamidation of tert-butyloxycarbonyl (Boc) activated secondary carboxamides with amines. Under non-conventional microwave techniques, the reactions were achieved under catalyst, additive, promoter and solvent-free conditions. The transamidation of a structurally diverse set of amides and amines was accomplished in good
已经开发出一种微波辅助、高度化学选择性的方案,用于叔丁氧基羰基 (Boc) 活化的仲酰胺与胺的转酰胺基作用。在非常规微波技术下,反应在催化剂、添加剂、促进剂和无溶剂条件下完成。一组结构多样的酰胺和胺的转酰胺基化反应以良好至优异的产率完成。该方法的显着特点包括操作简单、底物范围广泛、官能团耐受性、实用性和可扩展性。
