Racemic 2,6-dimethyioctyl formate (1), a synthetic analog of the aggregation pheromone of two species ofTribolium beetles, has been obtained in six steps and in 28 % overall yield starting from methyl ethyl ketone, vinyl bromide, and 2-methylpropenal. The key step of the synthesis is the sigmatropic [3,3]-rearrangement of 4-ethyl-2,4-dimethyl-1,5-hexadien-3-ol (5) to 2,6-dimethyl-5-octenal (6).
外消旋甲酸 2,6-二甲基辛基酯 (1) 是两种 Tribolium 甲虫聚集信息素的合成类似物,从甲基乙基酮、乙烯基溴和 2-甲基丙烯醛开始,分六个步骤以 28% 的总产率获得。合成的关键步骤是 4-乙基-2,4-二甲基-1,5-己二烯-3-醇 (5) 向 2,6-二甲基-5-辛烯醛 ( 6).
