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 R
1
, R
2
, and R
3
individually represents hydrogen or methyl), comprising reacting a 3-alkoxy-2-cyclohexen-1-one derivative represented by the following formula (2): (wherein R
1
, R
2
, and R
3
have the same meanings as above, and R
4
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.
一种生产以下式子(1)所代表的环己烯酮长链醇的方法:(其中A代表C10-C18的烷基或烯基,R1、R2和R3各自代表氢或甲基),包括将以下式子(2)所代表的3-烷氧基-2-环己烯-1-酮衍生物(其中R1、R2和R3的含义同上,R4代表C1-C5的烷基)与由硅基化保护C10-C18ω-卤代醇的羟基所制备的Grignard试剂反应,并水解反应产物。本发明的方法可以减少反应步骤,易于操作,成本也较低,因此在工业上具有实用价值。
