Photolysis of 1,3-dimethyl-5-nitro-6-benzylidenemethylhydrazinouracil (IV) resulted in the formation of 1,5,7-trimethyl-3-phenyl-4,6 (5H, 7H)-pyrazolo (3,4-d) pyrimidinedione (V) and 3,4,6-trimethyl-5,7 (4H, 6H)-triazolo (4,5-d) pyrimidinedione 1-oxide (VI). Upon irradiation of 1,3-dimethyl-5-nitro-6-acetophenylidenemethylhydrazinouracil (VIII), however, VI was obtained exclusively in excellent yield. On the basis of mechanistic consideration on these photocyclizations, a new photochemical synthesis of condensed 3-alkyltriazole 1-oxides was developed.
