C–H Activation-Engaged Synthesis of Diverse Fused-Heterocycles from the Reactions of 3-Phenyl-1,2,4-oxadiazol-5(2H)-ones with Vinylene Carbonate

We report the condition-controlled C–H activation-engaged reactions of 3-phenyl-1,2,4-oxadiazol-5(2H)-ones with vinylene carbonate, straightforwardly constructing four divergent fused-heterocycles by tuning the reaction conditions in a one-pot manner.
