A facile conversion of 6-(2-arylidenehydrazineyl) purines to [1,2,4] triazolo [3,4-i] purines is presented using PhI(OAc)2 as oxidant in only 10 min under room temperature. This approach is metal-free, wide functional group tolerant, and provides an efficient and convenient method to synthesize purine-fused tricyclics.
