Abstract


Treatment of oxazolone with hydrazine hydrate at room temperature gave the (Z)-configurated isomer hydrazide (Z)- (high yield). However, refluxing with hydrazine hydrate yielded the (E)-configurated isomer hydrazide (E)- (low yield).The hydrazide derivative (Z)- has been utilized as synthon for the synthesis of 1,2,4-triazinone, imidazolone, and oxadiazole derivatives through appropriate routes. The thiosemicarbazide and semicarbazide derivatives are synthesized by different routes. The structures of the new compounds were established on the basis of IR, 1H-NMR, mass spectral data, and elemental analysis.
