  描述：

  Methanesulfonic acid (E)-7-methyl-non-5-enyl ester 在 magnesium 、 sodium iodide 作用下， 以 四氢呋喃 、 丙酮 为溶剂， 反应 2.0h， 生成 (E)-12-methyltetradec-10-en-1-ol

  摘要：

  Reaction of 2-vinyltetrahydrofuran and 2-vinyltetrahydropyran with ethylmagnesium bromude in the presence ot titanium(IV) isopropoxide afforded in moderate selectivity trans-4-octen-1-ol and trans-5-nonen-1-ol respectively. Best yields and high stereochemical purity of products were obtained in ethylation under these conditions of 2-(cis-1-propenyl)tetrahydrofuran, 2-(cis-1-proprnyl)- and 2- (trans-1-propenyl) tetrahydropyran. It is assumed that the key organometallic intermediate formed was diisopropoxy-titanacycloprpopane, and direction of its addition to the doubel bond governed the streochemistry of the resulting product. The obtained trans-4-octen-1-ol and trans-7-methyl-5-nonen-1-ol were applied as initial products in the synthesis of sex pheromones of lesser plum worm (Grafolita funebrana) and tea leaf roller moth (Adoxophyes sp).
