摘要: New Cyclic Systems from Heterocyclic 5-Substituted Tetrazole Derivatives The easily accessible 5-substituted tetrazole derivatives 1 and 2 react with sodium nitrite, ortho esters, some aldehydes, bromoacetyl bromide to give the new tetrazolo-triazines 3 or 4, -pyrimidines 5 6, -5,6-dihydropyrimidines 7 -diazepinones 8.
