  • Regioselective SN2 Opening of Vinylic Epoxides with Trialkylzincates and Trialkylaluminates
    作者:Olivier Equey、Emmanuel Vrancken、Alexandre Alexakis
    DOI:10.1002/ejoc.200300759
    日期:2004.5
    The use of trialkylorganozincates and tetraalkylaluminates allows regioselective SN2 nucleophilic opening of vinylic epoxides. The reaction occurs with an anti-substitution pattern and can be applied to a wide range of substrates. We also show that the solvent and the structure of the epoxide have an influence on the substitution products ratio.
    三烷基有机锌酸盐和四烷基铝酸盐的使用允许乙烯基环氧化物的区域选择性 SN2 亲核打开。该反应以反取代模式发生,可应用于多种底物。我们还表明,溶剂和环氧化物的结构对取代产物比率有影响。
  • Scope and Limitation of Organocuprates, and Copper or Nickel Catalyst-Modified Grignard Reagents for Installation of an Alkyl Group onto <i>cis</i>-4-Cyclopentene-1,3-diol Monoacetate

    日期:2001.8.1
    NiCl(2)(tpp)(2), NiCl(2)(dppf), and NiCl(2)(dppp) furnished the best result to produce 2a. The CuCN-based protocol was then applied to other alkyl Grignard reagents, which include Me, Et, (CH(2))(3)Ph, c-C(6)H(11), (CH(2))(6)OMOM, (CH(2))(9)CH=CH(2), and CH(2)Ph as the alkyl group (R(T)). In addition, the Mitsunobu inversion of 2a and 3a afforded the corresponding cis isomers stereoselectively with AcOH
    用两种类型的试剂研究了标题化合物1的烷基化。一种是衍生自R(T)MgX(X = Cl,Br)和CuX(X = CN,I)的试剂,另一种是在催化剂存在下的R(T)MgX。首先,用BuCu(CN)(MgX),Bu(2)Cu(CN)(MgX)(2),BuMgX / CuCN(10 mol%),BuCu(衍生自BuMgCl和CuI)和BuMgCl /在THF或Et(2)O中的CuI(10 mol%)。我们发现反式1,4-异构体2a和/或反式1,2-异构体3a仅用这些试剂生产,BuMgX / CuX的化学计量和溶剂的选择对于获得高区域选择性和高效收率至关重要。与Bu(2)Cu(CN)(MgCl)(2)和BuMgCl / CuX(X = CN,I; 10 mol%)均在THF中反应生成2a,其区域选择性为93-94%,产率为87-92%。另一方面,BuCu(CN)(MgX)在THF中 Et(2

    日期:2002.7
    Abstract Alkylation of the acetates derived from 4-phenyl- and 4-butyl-2-cyclopenten-1-ols 2 was investigated with copper reagents derived from n -BuMgX (X=Cl, Br) and CuCN in 2:1 and 1:1 ratios in THF and in Et 2 O. cis 1,4-Isomers 4a , b (R=Ph, n -Bu) were produced regioselectively from the corresponding trans acetates 3a , b with the reagent in a 2:1 ratio of BuMgCl and CuCN in THF, while the BuMgBr-based

  • Catalytic Regiodivergent Kinetic Resolution of Allylic Epoxides:  A New Entry to Allylic and Homoallylic Alcohols with High Optical Purity
    作者:Mauro Pineschi、Federica Del Moro、Paolo Crotti、Valeria Di Bussolo、Franco Macchia
    DOI:10.1021/jo035674h
    日期:2004.3.1
    A novel regiodivergent kinetic resolution of a series of allylic epoxides with alkylzinc reagents is described. Results demonstrate the potential of chiral copper-phosphoramidite catalysts for enantiomer differentiation of allylic epoxides, allowing a chiral catalyst-stereoregulated synthesis of cyclic allylic and homoallylic alcohols with high optical purities.
