Facile synthesis of 9H-s-triazolo- [3,4-i]purin-5(6H)-ones

New tricyclic heterocycles, 9H-s-triazolo[3,4-i]purin-5(6H)-ones(2, 3), were prepared from 6-methylthio-7H-purin-2(3H)-ones (5a, 5d).

s-Triazolo(3,4-I)purine derivatives

There are disclosed s-triazolo[3,4-i]purine derivatives represented by formula: STR1 wherein Y-Z represents STR2 R4 represents hydrogen, alkyl, substituted or unsubstituted aromatic heterocyclic group or substituted or unsubstituted aryl; and X2 represents oxygen, sulfur or NH; each of R1 and R2 independently represents hydrogen, alkyl, cycloalkyl, aralkyl or substituted or unsubstituted aryl; R3 represents alkyl, cycloalkyl, aralkyl or substituted or unsubstituted aryl; X1 represents oxygen or sulfur; and represents a single bond or a double bond or pharmaceutically acceptable salts thereof.
