摘要

Alkaloids containing azaquaternary pyrroloazepine skeletons including cephalotaxine [1] and stemonamine [2] are an important class of bioactive molecules in nature. How to directly and enantioselectively construct the azaquaternary pyrroloazepine skeleton remains a challenge. Desymmetrization reactions, which are used to synthesize chiral molecules, are proving to be a powerful method, and variations of this type of reaction have been well ...
