  • A Convenient Transformation of 2-Alkylidenecycloalkanones into Alkyl-Substituted Bicyclo[n.1.0]alkan-1-ols: Application to the Synthesis of Capsaicin
    作者:Oleg Kulinkovich、Dzmitry Kananovich、Dzmitry Zubrytski

    日期:2010.4
    Treatment of 2-alkylidenecycloalkanones with hydrogen iodide in benzene and subsequent reaction of the obtained β-iodo ketones with zinc dust in THF in the presence of chlorotrimethyl­silane or titanium(IV) chlorotriisopropoxide led to exo- and endo-(n+3)-alkylbicyclo[n.1.0]alkan-1-ols in high yields. Cyclization of the intermediate β-iodo ketones under these conditions proceeded in a moderate to good diastereoselectivity, and the resulted bicyclic cyclopropanols were easily separated by column chromatography over silica gel. exo-7-Isopropylbicyclo[4.1.0]heptan-1-ol obtained in this manner was efficiently employed as a key intermediate in the synthesis of capsaicin.
    用氢碘酸处理2-烷基烯烃环酮,并在苯中进行反应,随后用锌粉在四氢呋喃中,在三甲基氯硅烷或四氯化钛三异丙基氧化物的存在下与所得到的β-碘酮反应,得到了高产率的外型和内型(n+3)-烷基双环[n.1.0]烷-1-醇。在这些条件下,中间体β-碘酮的环化反应表现出适度到良好的非对映选择性,所得到的双环环丙醇可以通过硅胶柱层析轻松分离。这种方法获得的外型7-异丙基双环[4.1.0]庚醇被有效地用作辣椒素合成中的关键中间体。
  • Cascade Biotransformations via Enantioselective Reduction, Oxidation, and Hydrolysis: Preparation of (<i>R</i>)-δ-Lactones from 2-Alkylidenecyclopentanones

    日期:2013.5.3
    cascade biotransformation involving enantioselective reduction of a C═C double bond, Baeyer–Villiger oxidation, and lactone hydrolysis was developed as a green and sustainable tool for synthesizing enantiopure δ-lactones. One-pot cascade biotransformations were achieved with Acinetobacter sp. RS1 containing a novel enantioselective reductase and an enantioselective lactone hydrolase and Escherichia coli

  • Enoyl acyl carrier protein reductase (FabI) catalyzed asymmetric reduction of the CC double bond of α,β-unsaturated ketones: preparation of (R)-2-alkyl-cyclopentanones
    作者:Ji Liu、Jinchuan Wu、Zhi Li
    DOI:10.1039/c4cc04150j
    日期:——
    Enoyl-ACP reductase (FabI) was identified as a non-OYE 'ene'-reductase for asymmetric reduction of the C=C double bond of alpha, beta-unsaturated ketones. Reduction of several 2-alkylidenecyclopentanones with A-FabI and E-FabI gave (R)-2-alkylcyclopentanones in 95-90% and 70-81% ee, respectively. The product ee was improved to 99-98% in high yield by subsequent one-pot biooxidation.

    Novel bicyclic ketones having the structure: ##STR1## wherein R is a C.sub.1 -C.sub.5 alkyl group, either straight-chain or branched, and saturated analogs have been prepared. These compounds exhibit floral and woody odors and/or desirable flavor properties, and are useful as fragrance and/or flavor materials. The compounds are conveniently prepared from alkylidene cyclopentanones by Michael addition with alkyl metalloacetoacetates and subsequent decarboxylative cyclization of the adducts. The saturated analogs may then be prepared by hydrogenation.
