A copper-catalyzed asymmetric propargylic amination with a chiral ketimine P,N,N-ligand that proceeds via decarboxylation of propargyl carbamates has been developed. The reaction can be performed under the mild condition for a broad range of substrates, providing the corresponding propargylic amines in high yields and with up to 97% ee. This reaction represents a new and facile access to optically
已经开发了通过手性酮亚胺P,N,N-配体的铜催化的不对称炔丙基胺,其通过炔丙基氨基甲酸酯的脱羧而进行。该反应可在温和条件下对多种底物进行,从而以高收率和高达97%ee提供相应的炔丙基胺。该反应代表了容易获得光学活性的炔丙基胺的新途径。
