A Convenient Synthesis of Prenylated Isoflavones: Synthesis of Licoricone and Related Compounds

The condensation of 6',7-bis(benzoyloxy)-2',4'-dimethoxyisoflavone (18) with 2-methyl-3-buten-2-ol, followed by hydrolysis of the resultant 6',7-bis(benzoyloxy)-2',4'-dimethoxy-3'-(3-methyl-2-butenyl)isoflavone (19) gave 6',7-dihydroxy-2',4'-dimethoxy-3'-(3-methyl-2-butenyl)-isoflavone (licoricone) (1).Its isomer, 6',7-dihydroxy-2',4'-dimethoxy-5'-(3-methyl-2-butenyl)-isoflavone (2), was also synthesized from 7-benzoyloxy-6'-hydroxy- or 6',7-bis(benzoyloxy)-2',4'-dimethoxy-5'-(3-methyl-2-butenyl)isoflavone (11 or 20).Keywords - isoflavone; selective prenylation (3-methyl-2-butenylation); prenylated isoflavone; 6',7-dihydroxy-2',4'-dimethoxy-3'-(3-methyl-2-butenyl)isoflavone (licoricone); 6',7-dihydroxy-2',4-dimethoxy-5'-(3-methyl-2-butenyl)isoflavone; 6-hydroxy-2,4-dimethoxybenzaldehyde
