Abstract

Summary: We describe the preparation of the title compound 2b via aza-Wittig reaction of N- Boc-triphenyliminophosphorane (6) with 4-cyanobenzaldehyde followed by Oxone oxidation of the resulting imine 5b. Oxaziridine 2b is a stable, crystalline solid, which transfers under mild conditions its N-Boc fragment to primary and secondary amines (to give Ng-Boc- hydrazines) and enolates (to give N-Boc-amino derivatives).
