A process for producing cyclohexenone long-chain alcohol represented by the following formula (1): (wherein A represents a C10-C18 alkylene or alkenylene group, and each of R1, R2, and R3 individually represents hydrogen or methyl), comprising reacting a 3-alkoxy-2-cyclohexen-1-one derivative represented by the following formula (2): (wherein R1, R2, and R3 have the same meanings as above, and R4 represents a C1-C5 alkyl group) with a Grignard's reagent prepared by protecting the hydroxyl groups of C10-C18 ω-halogenoalcohol through silylation, and hydrolyzing the resultant reaction product. The process of the present invention for producing cyclohexenone long-chain alcohol requires a reduced number of reaction steps, can be performed with ease and with reduced production cost, and thus finds utility in the industry.
通过保护C10-C18 ω-卤代醇的羟基,通过硅化反应制备格氏试剂,然后与以下公式(2)所代表的3-烷氧基-2-环己烯-1-酮衍生物发生反应(其中R1、R2和R3具有与上述相同的含义,R4代表C1-C5烷基),从而制备由以下公式(1)表示的环己烯酮长链醇的方法:(其中A表示C10-C18烷基或烯基,R1、R2和R3中的每一个单独表示氢或甲基),并水解生成的反应产物。本发明的制备环己烯酮长链醇的方法需要较少的反应步骤,易于操作,生产成本较低,因此在工业中具有实用性。
