A Mild and Efficient Synthesis of New 3-Phenylthienotriazolopyrimidine Derivatives Using Iodobenzene Diacetate

Abstract

New 3-phenylthieno[3,2-e][1,2,4]triazolo [4,3-c]pyrimidine 9a-i and 3-phenylthieno[2,3-e][1,2,4]triazolo[4,3-c]pyrimidine 10a-i derivatives were easily synthesized at rt in high yield by the oxidative cyclization of thienopyrimidinyl hydrazones using iodobenzene diacetate.
