Ring-opening reactions of N-tosylaziridines with water-soluble nucleophiles proceeded in a silica−water reaction medium. The system is applicable to a ring expansion of an aziridine with potassium thiocyanate, leading to a thiazolidine derivative.
The aza-addition of aziridines for vicinal-diamines was firstly disclosed under catalyst- and solvent-free conditions. Various aryl, alkyl and meso-bicyclic aziridines with a Ts-protecting group were tolerated, and aromatic amine-nucleophiles containing...

An unprecedented synthetic strategy is devised to generate β-aminoboronic acids from aziridines via a sequential process involving 1,2-iodoamine formation and radical borylation under light irradiation. A variety of aziridines including multiply substituted aziridines have been successfully employed as synthetic precursors, expanding their synthetic utility compared to previous methods. Mechanistic

[reaction: see text] Iron(III) porphyrin complexes Fe(Por)Cl are effective catalysts for aziridination of alkenes using bromamine-T as the nitrene source. The catalytic system can operate under mild conditions with alkenes as limiting reagents. The aziridination reaction is general and suitable for a wide variety of alkenes, including aromatic, aliphatic, cyclic, and acyclic olefins, as well as alpha,beta-unsaturated
