Pyrrolo[3,4-e][1,2,3]triazolo[1,5-a]pyrimidine and pyrrolo[3,4-d][1,2,3]triazolo[1,5-a]pyrimidine. New tricyclic ring systems of biological interest

Derivatives of the new ring system pyrrolo[3,4-e][1,2,3] triazolo[1,5-a]pyrimidine 6 were prepared in high yields in one step by reaction of 3-azidopyrrole 3 and substituted acetonitriles. Compound 6b rearranged, upon heating in dimethyl sulfoxide in the
