    γ-丁内酯的CO2活化及其在(±)-杂plexisolide E的全合成中的应用
    摘要:
    描述了一种高效的镍(0)催化在CO 2(1个大气压,气球)存在下用ZnEt 2对高炔丙醇进行高度区域和立体选择性加氢羧化反应,以合成α-亚烷基-γ-丁内酯。该催化剂具有很高的活性,可用于合成(光学活性)具有出色的区域和立体选择性以及良好的官能团耐受性的单环或双环α-亚烷基-γ-丁内酯。该反应的潜力已在(±)-杂plexisolide E的首次合成中得到了证明。

  • Stereoselective Synthesis of Polysubstituted Alkenes through a Phosphine-Mediated Three-Component System of Aldehydes, α-Halo Carbonyl Compounds, and Terminal Alkenes

    mediate the one‐pot Wittig reaction of aldehydes with α‐halo carbonyl compounds for the synthesis of 1,2‐disubstituted and trisubstituted alkenes in an excellent stereoselective fashion. Furthermore, the first one‐pot, three‐component reaction of aldehydes, α‐halo acetates, and terminal alkenes has been developed in the presence of PPh3 to produce trisubstituted alkenes with excellent E selectivity (see

    readily generated by the reaction of Ti(O-i-Pr)4 or ClTi(O-i-Pr)3 with 2i-PrMgX, resulted in an intramolecular nucleophilic acyl substitution (INAS) reaction to afford organotitanium compounds having a carbonyl functional group, in good to excellent yields. Thus, the treatment of alkyl alkynyl carbonates 2 or alkyl alkenyl carbonates 4 with 1 gave organotitanium compounds having a lactone and/or ester
    用低价钛试剂二异丙氧基(η2-丙烯)钛 (1) 处理炔属或烯属碳酸酯和酯,该试剂很容易通过 Ti(Oi-Pr)4 或 ClTi(Oi-Pr)3 与 2i- PrMgX 导致分子内亲核酰基取代 (INAS) 反应以提供具有羰基官能团的有机钛化合物,产率良好至极好。因此,用1处理烷基炔基碳酸酯2或烷基链烯基碳酸酯4得到具有内酯和/或酯基团的有机钛化合物。类似地,羧酸的烷基炔酸酯 10 或炔基酯 14 与 1 反应,分别得到具有环状或无环酮基团的有机钛化合物。因此,该反应在水解后提供来自 2 的五元或六元 α-亚烷基内酯和/或 α,β-不饱和酯,

    with an aldehyde to afford exclusively (E)-α-alkylidene-γ-butyrolactone. Interestingly, when the reaction was quenched below −20 °C or when it was carried out in the presence of metal complex such as zinc chloride, copper(I) iodide, or tributyltin chloride, (Z)-α-alkylidene-γ-butyrolactone was obtained as the major product. The stereoselectivity of this reaction was sensitive to the reaction temperature
    在 2.2 当量二异丙基氨基锂 (LDA) 存在下,用双 [乙氧基(硫代羰基)] 二硫化物处理 γ-丁内酯,生成 O-乙基 S-(四氢-2-氧代-3-呋喃基)二硫代碳酸酯的烯醇锂,其反应用醛生成仅 (E)-α-亚烷基-γ-丁内酯。有趣的是,当反应在 -20 °C 以下猝灭或在金属络合物(如氯化锌、碘化铜(I)或氯化三丁基锡、(Z)-α-亚烷基-γ-丁内酯)存在下进行时作为主要产品获得。该反应的立体选择性对反应温度和所用金属阳离子敏感。

    Treatment of γ-butyrolactone with bis[methoxy(thiocarbonyl)] disulfide in the presence of 2.2 equivalents of lithium diisopropylamide followed by the addition of aldehydes gave predominantly (E)-α-alkylidene-γ-butyrolactones. In contrast, when the reaction was carried out in the presence of metal salt such as cuprous iodide or zinc chloride, (Z)-α-alkylidene-γ-butyrolactone was obtained as the major
