A facile approach for the first total synthesis of prenylated flavonoids,(±)-abyssinone-Vl-4-O-methyl ether 1,(±)-abyssinoneIV -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 also first synthesized that features regioselective prenylation of 4-hydroxybenzaldehyde and crystallizing with petroleum ether from the reaction mixture by freeze-out effect.
