使用空气稳定的三甲基铝源DABAL-Me-3 [(DABCO)(AlMe 3)(2)],在微波辐射下进行酯和仲胺的容易的直接偶联以提供叔酰胺。在5-16分钟内完成的反应中,环仲胺获得了优异的产率(88-98%)。该方法可以扩展到在一锅法中使用NaH释放游离甲氧基胺形成Weinreb酰胺(从商业MeNHOMe中心点HCl中高达76%)。(C)2008爱思唯尔有限公司版权所有。
Facile direct coupling of esters and secondary amines to afford tertiary amides proceeds under microwave irradiation using the air-stable trimethylaluminium source DABAL-Me-3 [(DABCO)(AlMe3)(2)]. Excellent yields (88-98%) are attained for cyclic secondary amines in reactions that are complete in 5-16 min. The process can be extended to the formation of Weinreb amides (upto 76% from commercial MeNHOMe center dot HCl) in a one-pot procedure using NaH to liberate the free methoxyamine.
