    • An efficient method is proposed for the synthesis of an unsaturated alcohol of the general formula R--CH.dbd.CH(CH.sub.2).sub.n+1 OH, in which R is a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms and the subscript n is an integer in the range from 3 to 10, in which an acetate of the formula R--CH.dbd.CHCH.sub.2 OCOCH.sub.3 is subjected to a coupling reaction with a Grignard reagent of the formula X.sup.1 Mg(CH.sub.2).sub.n OMgX.sup.2, in which X.sup.1 and X.sup.2 are each a halogen atom, and then the reaction product is hydrolyzed. When the reaction product of the coupling reaction is reacted with acetic anhydride instead of hydrolysis, the corresponding acetate can readily be obtained. These unsaturated alcohols and acetates form a class of important biologically active compounds or intermediates thereof including sex pheromone compounds of insects.
    • 提出了合成通式为R-CH = CH(CH 2)n + 1OH的不饱和醇的有效方法,其中R为氢原子或具有1-10个碳原子的一价烃基,下标n 是3至10的整数,其中式R-CH = CHCH2OCOCH3的乙酸酯与式X1Mg(CH2)nOMgX2的格氏试剂进行偶联反应,其中X1和X2各自为 卤素原子,然后反应产物水解。 当偶联反应的反应产物与乙酸酐反应而不是水解时,可以容易地获得相应的乙酸酯。 这些不饱和醇和乙酸酯形成一类重要的生物活性化合物或其中间体,包括昆虫的性信息素化合物。
