An application of H-bonding interactions for directing the α-C–H oxidation of amines to amides and amino-ketones catalyzed by an organic photocatalyst is reported. The high efficiency of this method is demonstrated by the aerobic oxidation of pyrrolidines, diarylamines and benzylamines bearing urea groups with high yields and a wide substrate scope.

본 발명은 유기 아자이드 화합물로부터 질소에 치환기가 없는 이민을 발생시키고, 그와 아실 주개와의 반응을 통해 엔아마이드 화합물을 합성하는 방법에 관한 것이다. 본 발명의 제조 방법을 이용하면, 적절한 촉매를 사용하여 알파 수소를 가진 유기 아자이드로부터 연속한 질소 제거 및 1,2-수소 옮김 반응을 통해 질소에 치환기가 없는 이민을 생성하고, 이 이민과 아실 주개를 반응시켜 엔아마이드 화합물을 합성할 수 있다.
