Conjugated dienes were successfully aziridinated using a nitridomanganese complex as a nitrogen source. The reaction proceeded selectively and in good yield via [2+1] addition to give alkenylaziridines, with no evidence for the formation of any [4+1] addition products. The first asymmetric version of the reaction was revealed in the aziridination of diene 5 with chiral complex 1. (C) 2000 Elsevier Science Ltd.
