Diphenyl phosphorazidate with 4-dimethylaminopyridine and lithium perchlorate opens epoxides regio- and stereoselectively to give O- diphenylphosphoryl vicinal azidohydrins: For the α,β-epoxy ketones and esters, only the corresponding α-azidovinyl ketones
An improved procedure for the conversion of alkenes and glycals to 1,2- diazides using Mn(OAc)3·2H2O in acetonitrile containing trifluoroacetic acid

Alkenes and Glycals react with Mn(OAc3)·2H2O and NaN3 in 9:1 acetonitrile-trifluoroacetic acid to give 1,2-diazides in >80% yield. Allylic azides are formed by slow addition of NaN3 to a mixture of alkene, Mn(OA
Vinyliminophosphorane-mediated preparation of 2-arylquinoline and 4-aryl-1-azaanthraquinone derivatives. X-Ray crystal structure of 1,2-dihydro-3H-indazolo[2,3-a]quinolin-4-one

The reaction of the iminophosphorane derived from 3-azidocyclohexan-2-enone with substituted cinnamyl aldehydes affords 2-aryl-tetrahydroquinoline derivatives, which are easily converted into 2-arylquinolones. By contrast, iminophosphorane derived from 2-azidocyclohex-2-enone reacts only with α,β-unsaturated aldehydes without substituent at β-position to give 5,6-dihydro-8(7H)quinolinones. The iminophosphorane derived from 2-azido-1,4-naphthoquinone reacts with substituted cinnamyl aldehydes providing directly 4-aryl-1-azaanthraquinones. The crystal and molecular structure of 1,2-dihydro-3H-indazolo[2,3-a]quinolin-4-ono has been solved by X-Ray analysis.
