  Enzymes in organic synthesis. 27. Lipase-Catalyzed Synthesis of (5R,6S)-6-Acetoxyalkan-5-olides - homologues of the mosquito oviposition attractant pheromone

  摘要：

  Sixteen homologous (5R*,6S*)-6-hydroxyalkan-5-olides rac-5 and their acetoxy derivatives rac-6 were synthesized from the corresponding methyl (Z)-alk-5-enoates 3 by osmium(VIII) oxide catalyzed cis-hydroxylation to the dihydroxy esters rac-4 and hydrolysis of these esters followed by lactonization. Pancreatin-catalyzed lactonization of the dihydroxy esters rac-4 afforded enantiomerically enriched hydroxy lactones ent-5, five of which were obtained enantiomerically pure by recrystallization. Acetylation of the 6-hydroxyalkan-5-olides rac-5 by vinyl acetate catalyzed by the lipase SP 526 provided enantiomerically enriched 6-acetoxyalkan-5-olides 6 with an enantiomeric excess of more than 90% in nine cases. These compounds are known as mosquito oviposition attractant pheromone (6h) or its homologues.

  by the regio- and stereoselective ring opening of β, γ, and δ-lactones with unsaturated substituents at the ω-position using organocopper reagents such as halomagnesium diorganocuprates or Grignard reagents in the presence of copper(I) iodide. Both the organocopper reagents with primary, secondary, tertiary alkyl, and phenyl groups gave the corresponding carbon homologated alkenoic acids in good yields

  描述了通过 β、γ 和 δ-内酯的区域和立体选择性开环来制备 (E)-3-、(E)-4- 和 (E)-5- 烯酸的新合成方法在碘化铜 (I) 存在下，使用有机铜试剂如卤化二有机铜酸盐或格氏试剂在 ω 位去除不饱和取代基。具有伯、仲、叔烷基和苯基的有机铜试剂均以良好的产率得到相应的碳同系链烯酸。通过 ω-烯基内酯与二乙烯基-和二烯丙基铜酸盐的反应，也以良好的产率获得链二烯酸。利用β-异丙烯基-β-丙内酯的开环，很容易以良好的收率获得高萜类羧酸。
