Highly enantioselective hydrogenation of seven-membered cyclic imines, substituted dibenzo[b,f][1,4]oxazepines, was achieved, with up to 94% ee, by using the [Ir(COD)Cl](2)/(S)-Xyl-C(3)*-TunePhos complex as the catalyst in the presence of morpholine-HCl.
通过使用[Ir(COD)Cl](2)/(S )-Xyl-C(3)*-TunePhos配合物在吗啉-HCl的存在下作为催化剂。
