- Synthesis of 8,9-dihydro[1,2,4]triazolo[1,5-a]-quinazolin-6(7H)-one derivatives
-
Regioselectivity of the reactions of 1H-1,2,4-triazol-3-amines with 2-acyl-5,5-dimethylcyclohexane-1,3-diones and 2-dimethylaminomethylidene-5,5- dimethylcyclohexane-1,3-dione was studied. In all cases, the products were substituted 8,9-dihydro[1,2,4]triazolo[1,5-a]quinazolin-6(7H)-ones whose structure was determined by 1H and 13C NMR spectroscopy.
