专利号:US-4912253-A 优先权日:1988-06-06 标题 :Method for the preparation of an unsaturated alcohol or ester thereof 发明人:FUKUMOTO TAKEHIKO; YAMAMOTO AKIRA 权利人:SHINETSU CHEMICAL CO 摘要:An efficient method is proposed for the synthesis of an unsaturated alcohol of the general formula R--CHâ•?CH(CH 2 ) 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--CHâ•?CHCH 2 OCOCH 3 is subjected to a coupling reaction with a Grignard reagent of the formula X 1 Mg(CH 2 ) n OMgX 2 , in which X 1 and X 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.
