    Project supported by the National Natural Science Foundation of China (Nos. 21162021, 20962016), the Ningxia Natural Science Foundation (No. NZ1006), the Program for New Century Excellent Talents in University (No. NCET-09-0860) and the National Basic Research Program 973 of China (No. 2010CB534916).

A facile approach for the total synthesis of prenylated flavonoids, (?)-abyssinone-VI-4-O-methyl ether (1), (?)-abyssinone-IV-4'-O-methyl ether (2), (?)-abyssinone-V-4'-O-methyl ether (3) and (?)-sigmoidin E (4), has been described. The key intermediate 4-hydroxy-3,5-di-(3-methylbut-2-enyl)benzaldehyde (6) was synthesized that features regioselective prenylation of 4-hydroxybenzaldehyde and crystallizing with petroleum ether from the reaction mixture by freeze-out effect. All structures of new compounds were confirmed by IR, 1H NMR, MS and HRMS techniques.

Key words: prenylated flavonoind, (?)-abyssinone-VI-4-O-methyl ether, (?)-abyssinone-IV-4'-O-methyl ether, (?)- abyssinone-V-4'-O-methyl ether, (?)-sigmoidin E, total synthesis
