Abstract Vinyl-substituted 1,3,4-oxadiazoles can be efficiently synthesized through acylation, cyclocondensation, and oxidation–elimination reaction from polystyrene-supported α-selenopropionic acid and acid hydrazides. This new solid-phase organic synthesis method could provide the target compounds in good yield and purity, with advantages of decreased volatility and simplification of workup procedure
