Abstract: Ten kinds of imidazolyl isoflavone derivatives were synthesized from resorcinol and substituted phenylacetic acid as start materials via five-steps. The structures of the ten target compouds were confirmed via 1H NMR, 13C NMR and elemental analysis. The reaction time was shortened greatly in many reaction process by a microwave-mediated method. The antioxidative activities of ten target compounds were researched. Among them the 4'-hydroxy-2-methyl-7-[3-(1-imidazolyl) propoxy] isoflavone has a strongly capacity of scavenging radical.

Key words: Isoflavone, Imidazole, Imidazolyl isoflavone derivatives, Microwave-mediated synthesis, Antioxidative activity
