A highly stereoselective and practical synthesis of α-trichloromethyl amines by nucleophilic trichloromethylation of N-(tert-butylsulfinyl)imines with chloroform was achieved. The obtained α-trichloromethyl amines can be further transformed into chiral 2,2-dichloroaziridines through an intramolecular nucleophilic substitution methodology. 2,2-Dichloroaziridines can also be produced directly from chloroform
通过N-(叔丁基亚磺酰基)亚胺与氯仿的亲核三氯甲基化,实现了高度立体选择性和实用的α-三氯甲基胺的合成。可以通过分子内亲核取代方法将获得的α-三氯甲基胺进一步转化为手性2,2-二氯氮丙啶。也可以通过一锅法由氯仿和N-(叔丁基亚磺酰基)亚胺直接生产2,2-二氯氮丙啶。
