摘要
对松叶蜂 diprion pini性信息素活性组分 3,7-二甲基 -2 -十三碳醇乙酸酯的全合成进行了研究 .以丙二酸二乙酯和 2 ,3-环氧丁烷为原料 ,分别合成了两个重要结构单元—— 2 -甲基 -1-辛烷基锂和 3,4-二甲基 -γ-丁内酯 .2 -甲基 -1-辛烷基锂与 3,4-二甲基 -γ-丁内酯反应 ,得到的酮醇再经黄鸣龙还原 ,得到 3,7-二甲基 -2 -十三碳醇 ,经酯化 ,得到 3,7-二甲基 -2
The total synthesis of 3,7 dimethyl 2 tridecanyl acetate,the active component of the sex pheromone of diprion pini,was investigated in this paper.The two key synthins blocks,2 methyl octan 1 yl lithium and 3,4 dimethyl γ butyrolactone,were obtained from diethyl malonate and 2,3 epoxybutane.2 Methyl octan 1 yl lithium reacted with 3,4 dimethyl γ butyrolactone to yield the ketoalcohol and then followed by Huang Minlong reduction to afford 3,7 dimethyl 2 tridecanol,acylated with acetic anhydide to give 3,7 dimethyl 2 tridecanyl acetate.
