N-Phosphinoyloxaziridines possessing an activating 3-CF3 substituent oxidise alkenes to epoxides at 35-45°C. Esters can be oxidised to α-hydroxyesters via their lithium enolates by various 3-subsituted N-phosphinoyloxaziridines. Stereoselectivity is observed in both these oxidations.

Abstract
N-Phosphinoyloxaziridines possessing an activating 3-CF3 substituent oxidise alkenes to epoxides at 35-45°C. Esters can be oxidised to α-hydroxyesters via their lithium enolates by various 3-subsituted N-phosphinoyloxaziridines. Stereoselectivity is observed in both these oxidations.File in questo prodotto:
