transamidation of primary and tertiary amides with a range of aryl, heteroaryl, and aliphatic amines using potassium tert-butoxide. The reaction proceeds at room temperature under transition-metal-free conditions providing secondary amides in high yields. Moreover, reaction of cyclopropyl amine with tertiary amides proceeds with ring-opening to provide a rapid access to enamides.
这项工作公开了使用叔丁醇钾将伯酰胺和叔酰胺与一定范围的芳基,杂芳基和脂肪族胺进行氨基转移。反应在室温下在无过渡金属的条件下进行,以高收率提供仲酰胺。此外,环丙胺与叔酰胺的反应以开环进行以提供对酰胺的快速访问。
