Facile synthesis of (�)-2,6-dimethyloctan-1-ol formate, the biologically active analog of the smaller flour beetle aggregation pheromone, from 1-allyloxy- and 1-benzyloxy-2,6-dimethyl-2,7-octadienes, the telomers of isoprene with allyl and benzyl alcohols

of isoprene with allyl, benzyl, 2-chloroethyl and methyl alcohols on π-allylpalladium complex catalysts was carried out. The structures of the obtained telomers were determined by1H NMR spectroscopy. 1-Alkoxy-2,6-dimethyl-2,7-octadiene is a predominant telomer. 2,6-Dimethyloctan-1-ol, which reacts with HCOOH to give (±)-2,6-dimethyloctan-1-ol formate in high yield, was obtained from 1-allyloxy- and
对异戊二烯与烯丙基、苄基、2-氯乙基和甲醇在 π-烯丙基钯配合物催化剂上的调聚进行了仔细研究。所得调聚物的结构由 1 H NMR光谱确定。1-烷氧基-2,6-二甲基-2,7-辛二烯是主要的调聚物。2,6-Dimethyloctan-1-ol 与 HCOOH 反应以高产率得到 (±)-2,6-dimethyloctan-1-ol 甲酸酯,从 1-allyloxy- 和 1-benzyloxy-2,6- 获得二甲基-2,7-辛二烯通过去除烯丙基和苄基保护基团以及双键氢化。
