A process for producing geranylgeraniol is provided, which comprises the steps of subjecting a mixture of at least one ester derivative wherein one or more carbon-carbon double bonds in the molecule are in cis form represented by the general formula (1):
wherein R represents an aromatic group which can be substituted with at least one substituent, or a higher aliphatic group having from 7 to 25 carbon atoms, and wavy lines, respectively, represent a state where each carbon-carbon double bond can be present in cis or trans form, and an ester derivative of the general formula (2):
wherein R is as defined above, to crystallization to obtain the ester derivative of the formula (2) selectively, and hydrolyzing the thus obtained ester derivative.
本发明提供了一种生产香叶基橙皮酚的工艺,该工艺包括以下步骤:将至少一种酯衍生物的混合物置于通式(1)中,其中分子中的一个或多个碳碳双键以顺式形式存在:
其中 R 代表可被至少一个取代基取代的芳香族基团或具有 7 至 25 个碳原子的高脂族基团,波浪线分别代表每个碳碳双键可以顺式或反式形式存在的状态,以及通式(2)的酯类衍生物:
其中 R 如上文所定义,结晶以选择性地获得式(2)的酯衍生物,并水解由此获得的酯衍生物。
