    Tandem radical cyclization of acyclic homoallylic xanthates: cyclopentannulated .gamma.-thionolactone and .gamma.-lactones
    摘要:
    The first tandem radical cyclization of linear homoallylic xanthates was explored. Homoallylic xanthates prepared from alpha,beta-unsaturated esters were easily cyclized by tin hydride with an radical initiator to give the corresponding thionolactone annulated cyclopentane skeleton in a high yield. The stereochemistry of cyclized products was also discussed. Thionolactones obtained were oxidized chemoselectivity with m-CPBA under neutral condition to afford gamma-lactones in a high yield.

    摘要:
    将已建立的有机膦的两个电子亲核催化与光氧化还原有机催化相结合,发现了机械上不寻常的吉斯偶联反应。除了解决传统光氧化还原与缺电子炔烃偶联的局限性之外,这些研究还证明了将传统亲核膦有机催化和光氧化还原事件结合起来的反应设计的可行性。

  • Facile synthesis of α, β-unsaturated esters through a one-pot copper-catalyzed aerobic oxidation-Wittig reaction
    作者:Cheng Ren、Zhenyu Shi、Weijie Ding、Zhiqing Liu、Huile Jin、Xiaochun Yu、Shun Wang

    日期:2018.1
    An efficient one-pot synthesis of α, β-unsaturated esters through the aerobic oxidation – Wittig tandem reaction of alcohols and phosphorous ylide is developed. This new method operates under mild reaction conditions, and uses CuI/TEMPO (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) as co-catalyst and air (O2) as the oxidant. It tolerates a wide range of functionalized benzylic alcohol and aliphatic

    作者:Brett R. Ambler、Ryan A. Altman
    DOI:10.1021/ol402780k
    日期:2013.11
    this transformation typically requires four-step processes, specialty chemicals, and/or stoichiometric metals to access the trifluoromethyl-containing product. A two-step copper-catalyzed decarboxylative protocol for converting allylic alcohols to trifluoromethanes is reported. Preliminary mechanistic studies distinguish this reaction from previously reported Cu-mediated reactions.
    新合成化反应的发展对医药、农业和材料化学具有重要意义。鉴于醇的普遍性和可及性,将醇转化为三氟甲烷的方法是可取的。然而,这种转变通常需要四步过程、特殊化学品和/或化学计量属才能获得含三甲基的产品。报道了用于将烯丙醇转化为三氟甲烷的两步催化脱羧方案。初步的机理研究将这种反应与先前报道的介导的反应区分开来。

    allylic alcohols have been prepared and submitted to a Mitsunobu reaction with dithioacetic acid. Allyl dithioesters were deprotonated by LDA at −30°C and resulting enethiolates were quenched with iodomethane to afford quantitatively S-allyl ketenedithioacetals. These precursors undergo a thio-Claisen rearrangement under smooth conditions: room temperature or heating at 101°C. The diastereoselectivity of
