N-Acylaziridines are important starting materials for the synthesis of chiral amine derivatives. The traditional methods for producing these activated aziridines have significant drawbacks. The gram scale synthesis of N-acylaziridines by deprotection of N-tosylaztridines and reprotection with N-hydroxysuccinimide derivatives is described. Mono- and disubstituted aziridines perform well, with complete retention of stereochemical purity. The consistently moderate yields are linked to the N-tosylaziridine deprotection step, while acylation with N-hydroxysuccinimide derivatives is highly efficient.
