Fused Mesoionic Heterocycles: Synthesis of 1,3,4-Oxadiazolopyridine and 1,3,4-Thiadiazolopyridine Derivatives

Two general methods are reported for the preparation of mesoionic derivatives of 1,3,4-oxadiazolopyridine and 1,3,4-thiadiazolopyridine from 1-amino-4,6-diphenyl-2-pyridone (3) and 1-amino-4,6-diphenylpyridine-2-thione (4), respectively.The
