The first cobalt-catalyzed amide activation of N-Boc-amides, and their conversion into esters, is reported here. This new methodology presents a very practical process that does not require an inert atmosphere, uses an inexpensive cobalt catalyst, and proceeds under mild reaction conditions. This catalytic system has a broad substrate scope and has been shown to be highly efficient, with catalyst loadings
这里报道了N -Boc-酰胺的首次钴催化的酰胺活化,以及它们转化成酯的过程。这种新方法提供了一种非常实用的方法,不需要惰性气氛,使用廉价的钴催化剂,并且可以在温和的反应条件下进行。该催化体系具有广泛的底物范围,并且已经证明是高效的,催化剂负载量低至1mol%。
