摘要:

对以己内酯为起始原料合成辣椒素的工艺进行全新改进, 直接以6-溴己酸乙酯为起始原料, 经6步反应合成了目标化合物辣椒素及其同系物辣椒酯.

关键词: 辣椒素, 8-甲基-E-6-壬烯酸(4'-羟基-3'-甲氧基)苄酯, Wittig反应

Abstract:

Capsaicin and (E)-4-hydroxy-3-methoxybenzyl-8-methylnon-6-enoate were important intermediate of medicine. This research proposed a new method for synthesizing them from 6-bromohexanoic ester by Wittig reaction to give (Z)-8-methyl-6-nonenoic acid(4), then treated by nitrous acid and NaNO2 to induce Z→E isomerization reaction of the carbon-carbon double bond, then followed by condensation reaction to give product in an overall yield of 31%. The method is more convenient than traditional methods.

Key words: Capsaicin, (E)-4-hydroxy-3-methoxybenzyl-8-methylnon-6-enoate, Wittig reaction
