Diphenyl phosphorazidate with 4-dimethylaminopyridine and lithium perchlorate opens epoxides regio-and stereoselectively to give O-diphenylphosphoryl vicinal azidohydrins. For the o~,13-epoxy ketones and esters, only the corresponding ~x-azidovinyl ketones and esters were directly obtained, respecti
