✦ Synopsis

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, respectively.

## Abstract Diphenyl phosphorazidate (DPPA) was used as the azide source in a one‐pot synthesis of 2,2‐disubstituted 3‐amino‐2__H__‐azirines 1 (__Scheme 1__). The reaction with lithium enolates of amides of type 2, bearing two substituents at C(2), proceeded smoothly in THF at 0Β°; keteniminium azid

## AlXll.Z& A series of epoxides from reaction of substituted deltacyclenes with metu-chloroperbenzoic acid are reported. These compounds were found to react with BFs.Et20 in MeOH/&O to yield ring-opened products. Rearrangements were noted in some cases depending on the substitution pattern. We
