Reaction of N-(trans-2,3-diphenylaziridin-1-yl)imines with alkyllithiums and organocuprates afforded the desired addition products after consecutive fragmentations along with liberation of stilbene and nitrogen gas, while the reaction of N-(2-phenylaziridin-1-yl)imines under similar conditions gave an anomalous by-product.

的反应ñ - (反式-2,3- diphenylaziridin -1-基)亚胺用,得到所需的加成产物与芪和氮气的解放沿着连续分片之后烷基锂和有机铜,而反应ñ - (2- phenylaziridin-在类似条件下的1-yl)亚胺产生异常的副产物。使用未活化的烯烃和炔烃作为受体,N-(反式-2,3-二苯基叠氮基-1-基)亚胺的阴离子环化反应顺利进行,从而以高收率得到环化产物。
