Synthesis of oxaziridines

Recent Literature

An efficient and highly enantioselective Payne-type oxidation of N-sulfonyl imines exhibits broad substrate generality and unique chemoselectivity based on the combined use of hydrogen peroxide and trichloroacetonitrile under the catalysis of P-spiro chiral triaminoiminophosphorane.

The asymmetric Payne oxidation of N-sulfonyl aldimines catalyzed by a P-spiro chiral triaminoiminophosphorane enables a practical synthesis of optically active N-sulfonyl oxaziridines with high efficiency and an excellent level of enantioselectivity. The versatility of this method was demonstrated by the diastereoselective kinetic oxidation of racemic α-chiral N-sulfonyl imines.
