Enantiomeric 3,7-Dimethylocta-1,7-dienes as Useful Chiral Building Blocks. A New Access to Both Optical Antipodes of Natural (E)-3,7-Dimethyloct-2-ene-1,8-diol and (E)-3,7-Dimethyloct-2-ene-1,8-dicarboxylic Acid

Ozonolysis of the easily available monoterpenoids (−)-1 and (+)-1 leads in high yield to the ketoaldehydes (−)-4 and (+)-4, which serve as convenient intermediates for efficient new routes to both optical antipodes of the naturally occurring octenediol (E)-2 (Monarch butterfly secretion product) and octene-dicarboxylic acid (E)-3 (Callosobruchus chinensis sex pheromone). All steps proceed with almost
容易获得的单萜类化合物(-)- 1和(+)- 1的臭氧分解可高产率产生酮醛(-)- 4和(+)- 4,它们是便捷的中间体,可高效地连接到两种光学对映体天然存在的辛二醇(E)-2(帝王蝶分泌产物)和辛烯二羧酸(E)-3(Callosobruchus chinensis性信息素)。所有步骤几乎都会完全保留构型,从而确保合成具有高光学纯度的目标化合物。
