and cycloaddition of azide anion to the resulting C-2 double bond. Transformation of the new fused heterocyclic iminophosphoranes on treatment with aqueous ethanolic ammonia gives carboxamidine derivatives of ν-triazole bearing a chiral trihydroxypropyl side-chain. Crystal structure of 5-( d -erythro-1′,2′,3′-trihydroxypropyl)-1,2,3-triazole-4-carboxamidine was established by X-ray crystallography
