Preparation and ring-opening reactions of N-diphenylphosphinyl vinyl aziridines
Predominantly (E)-N-diphenylphosphinyl vinyl aziridines are prepared by a reaction of N-diphenylphosphinyl imines with α-bromoallyllithium in the presence of freshly fused ZnCl2.

Synthesis of oxazolinyl aziridines
Abstract Aziridinyllithiums 4a and 4b , which are stable at low temperature, can be generated by deprotonation of 3a and 3b . Oxazolinyl aziridines 5a-j and 6a-b have been prepared by the reaction of oxazolinyl aziridinyllithiums 4a and 4b with electrophiles. Aziridines 6c and 6d were, instead, synthesized by a Darzens-like reaction

Organocatalyzed enantioselective desymmetrization of aziridines and epoxides
Enantioselective desymmetrization of meso-aziridines and meso-epoxides with various nucleophiles by organocatalysis has emerged as a cutting-edge approach in recent years.

N-Aminopyridinium reagents as traceless activating groups in the synthesis of N-Aryl aziridines
Aziridines are useful intermediates, present in important synthetic targets. Here, the authors show a strategy for the synthesis of N-aryl aziridines based on N-aminopyridinium reagents followed by Ni-catalyzed C–N cross-coupling of N-pyridinium ...
