  • Tandem Asymmetric Cyclopropanation/Cope Rearrangement. A Highly Diastereoselective and Enantioselective Method for the Construction of 1,4-Cycloheptadienes
    作者:Huw M. L. Davies、Douglas G. Stafford、Brian D. Doan、Jeffrey H. Houser
    DOI:10.1021/ja974201n
    日期:1998.4.1
    rhodium(II) (N-dodecylbenzenesulfonyl)prolinate (Rh2(S-DOSP)4, 1) in the presence of dienes results in a direct and highly enantioselective method for the formation of cis-divinylcyclopropanes. Combination of this process with a subsequent Cope rearrangement results in a highly enantioselective synthesis of a variety of cycloheptadienes containing multiple stereogenic centers.
    在二烯存在下,通过 (II) (N-十二烷基苯磺酰基) 脯酸 (Rh2(S-DOSP)4, 1) 分解乙烯基重氮乙酸酯,可以直接且高度对映选择性地形成顺式二乙烯基环丙烷。该过程与随后的 Cope 重排相结合,导致多种含有多个立体中心的环庚二烯的高度对映选择性合成。

    copper(I)-catalyzed vinylation of diazo compounds with vinylbenziodoxolone reagents (VBX) as partners is reported. The transformation tolerates diverse functionalities on both reagents delivering polyfunctionalized vinylated products. The strategy was successfully extended to a three-component/intermolecular version with alcohols. The obtained products contain synthetically versatile functional groups, such

  • Copper-Catalyzed Oxy-Alkynylation of Diazo Compounds with Hypervalent Iodine Reagents
    作者:Durga Prasad Hari、Jerome Waser
    DOI:10.1021/jacs.6b00278
    日期:2016.2.24
    Alkynes have found widespread applications in synthetic chemistry, biology, and materials sciences. In recent years, methods based on electrophilic alkynylation with hypervalent iodine reagents have made acetylene synthesis more flexible and efficient, but they lead to the formation of one equivalent of an iodoarene as side-product. Herein, a more efficient strategy involving a copper-catalyzed oxy-alkynylation
    炔烃在合成化学生物学和材料科学中有着广泛的应用。近年来,基于与高价试剂亲电炔基化的方法使乙炔合成更加灵活和高效,但它们导致形成一当量的芳烃作为副产物。在此,描述了一种更有效的策略,该策略涉及催化的重氮化合物与乙炔基苯并氧醇 (on)e (EBX) 试剂的氧炔化反应,该策略会产生作为唯一废物的氮气。该反应因其在 EBX 试剂和重氮化合物中的广泛范围而引人注目。此外,乙烯基重氮化合物选择性地提供烯炔作为单一几何异构体。
