[reaction: see text]. Regio- and stereodefined allylic N-sulfonylamines are synthesized in high yields and under experimentally straightforward conditions by reaction of N-sulfonylaziridines with excess dimethylsulfoniummethylide.

sulfonyl-activated aziridines using lithiated dithianes was investigated. Nucleophilic attack of lithiated dithianes on aziridines containing tert-butylsulfonyl (Bus) and 2-(trimethylsilyl)ethylsulfonyl (SES) demonstrated efficient ring cleavage to yield β-amino carbonyl equivalents, γ-lactam and syn- and anti-1,5-aminoalcohols. The first example of a ring-opening reaction of di-substituted aziridine using dithiane
