Effective routes for the synthesis of (S)-2-acetoxytridecane, the sex pheromone of the fruit flyDrosophila mulleri, and (S)-1-methylbutyl 2-methyl- and 2,4-dimethylpent-2E-enoates, components of the aggregationpheromone of the lesser grain borerRhyzopertha dominica, were developed on the basis of (S)-4-methylhex-5-en-1-yl tosylate accessible from (S)-(+)-dihydromyreene.

acetate in 58% yield by dilithium tetrachlorocuprate catalyzed cross-coupling with the Grignard reagent derived from n-octyl bromide; and reduction of both ester groups in the tosylate with lithiumaluminumhydride to (S)-pentan-2-ol (yield 79%), followed by its esterification with (2Е)-2-methylpent-2-enoyl or (2Е)-2,4-dimethylpent-2-enoyl chloride with 68 and 69% yields, respectively.
摘要 (2 S )-十三烷基乙酸酯(果蝇的性信息素)和 (2 Е )-2-methylpent-2-enoic 和 (2 Е )-2,4-dimethylpent-2-的( S )-1-甲基丁酯烯酸(Rhyzopertha dominica小螟虫的聚集信息素的成分)由市售的 5-hexen-2-one(烯丙基丙酮)合成,基于起始酮的总产率分别为 31.0、28.8 和 29.2%。该过程的关键步骤是 5-hexen-2-one 与Rhodococcus erythropolis А-25 放线菌的对映选择性生物还原为 ( S )-5-hexen-2-ol,产率为 77% ( ее98.4%) 和以下化学选择性反应:( S )-5-hexen-2-yl acetate 的臭氧裂解,然后在 88 中用 NaBH 4将过氧产物还原为 ( S )-5-hydroxypent-2-yl acetate

Several aliphatic 2-alkanols with varying chain length has been efficiently resolved by their acetylation using vinyl acetate/PPL in diisopropyl ether. The effect of solvent polarity, position and type of unsaturation and chain length has been probed. This has led to more convenient synthesis of some insect pheromones.

Syntheses are developed for 2S-tridecyl- and 2S-tridec-10E-enylacetates, sex pheromones of the fruit fly Drosophila mulleri and the Hessian fly Mayetiola destructor, respectively, that are based on ethyl-3S-hydroxybutanoate, a product from enzymatic reduction of ethyl acetoacetate by the soil yeast strain "80-1."
