摘要
利用温和的方法进行了异戊烯基黄酮(±)-abyssinone-VI-4-O-methyl ether,(±)-abyssinone-IV-4'-O-methyl ether,(±)-abyssinone-V-4'-O-methyl ether和(±)-sigmoidin E的全合成研究,同时通过对羟基苯甲醛的异戊烯基化以及在石油醚中低温结晶的方法合成了关键中间体4-羟基-3,5-二异戊烯基苯甲醛.所有新化合物的结构都经过IR,1H NMR,MS,HRMS确认.
A facile approach for the total synthesis of prenylated flavonoids, (黄文倩)-abyssinone-VI-4-O-methyl ether (1), (黄文倩)-abyssiuone-IV-4'-O-methyl ether (2), (黄文倩)-abyssinone-V-4'-O-methyl ether (3) and (黄文倩)-sigrnoidin E (4), has been de- scribed. The key intermediate 4-hydroxy-3,5-di-(3-methylbut-2-enyl)benzaldehyde (6) was synthesized that features regiose- lective 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.
