Synthesis and high resolution proton NMR studies on isomeric N-1-/N-2-, 5,7-trisubstituted-4,6-dioxo-4,5,6,7-tetrahydropyrazolo[3,4-d]pyrimidines

Unambiguous synthesis of all six possible 1/2, 5,7-trisubstituted (monobenzyl, dimethyl)-4,6-dioxo-4,5,67-tetrahydropyrazolo[3,4-d]pyrimidines has been described. High resolution (400 MHz) proton NMR data of these compounds (10, 13, 19, 25a, 25b and 25c)
