The first diastereoselective nitroaziridination of N-tosylaldimines with 1-bromonitroalkanes

The first expeditious nitroaziridination of N-tosylaldimines is reported. The protocol involves operationally simple catalyst-free reaction of N-tosylaldimines, 1-bromonitroalkanes and NaOAc to afford 2-nitro-1-tosylaziridines in excellent yields with high Z-diastereoselectivity in a one-pot procedure under ambient conditions.
