developed for the synthesis of substituted-1,3,4-oxadiazole-2(3H)-one derivatives via a novelone-pot, tandem procedure assisted by propylene oxide. The 5-substitued-1,3,4-oxadiazole-2(3H)-ones and 3,5-disubstitued-1,3,4-oxadiazole-2(3H)-ones were, respectively, obtained from three-component reaction of acylhydrazines, carbon disulfide, and propylene oxide, and four-componentreaction of acylhydarazines
