A New Synthesis of Pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-diones by Oxidative N-N Bond Formation of 6-Amino-5-(N-aryliminomethyl)uracils Using Iodobenzene Diacetate
Pyrazolo[3,4-d]pyrimidine-4,6-dione derivatives were efficiently synthesized via the intramolecular N-N bond coupling of 5-iminomethyl-6-aminouracil derivatives using iodobenzene diacetate. The oxidative coupling was also applied to the analogous N-O bond formation producing isoxazolo[3,4-d]primidine-4,6-dione derivatives.
