Synthesis of Licoisoflavone A and Related Compounds

2',4',5,7-Tetrahydroxyisoflavone was partially benzoylated with benzoyl chloride to give 7-benzoyloxy-2',4',5-trihydroxyisoflavone.The condensation of the 7-(benzoyloxy)isoflavone with 2-methyl-3-buten-2-ol, followed by the hydrolysis of the resultant 3'-(3-methyl-2-butenyl)isoflavone gave licoisoflavone A.Its 5'-(3-methyl-2-butenyl) isomer was also synthesized from 5-benzoyloxy-2',4',7-trihydroxyisoflavone in a similar manner.
