  • Stereoselective synthesis of enantiopure β, γ-disubstituted α-alkylideneγ-butyrolactones via A palladium(II) catalyzed cyclization
    作者:Guoxin Zhu、Xiyan Lu
    DOI:10.1016/0957-4166(95)00009-e
    日期:1995.2
    β, γ-disubstituted α-alkylidene-γ-butyrolactones with cis or trans relative configurations were synthesized in both optically active forms from readily available homochiral allylic 2-alkynoates by Pd(II) catalysis in the presence of CuX2 and LiX.
    在CuX 2和LiX的存在下,通过Pd(II)催化,由Pd(II)催化的易于合成的手性均烯丙基2-炔酸酯以光学活性形式合成具有顺式或反式构型的β,γ-二取代α-亚烷基-γ-丁内酯。
  • Palladium-Templated Regio- and Stereoselective Cyclization of 2'-Alkenyl 2-Alkynoates and Its Synthetic Applications
    作者:Jianguo Ji、Chunming Zhang、Xiyan Lu
    DOI:10.1021/jo00110a018
    日期:1995.3
    2'-Alkenyl 2-alkynoates undergo facile stereoselective cyclization to alpha-(haloalkylidene)-gamma-butyrolactones upon treatment with a catalytic amount of palladium complex in the presence of CuX(2) and LiX. When an alkyl group is introduced to the 1'-position of the alkenyl group, unsubstituted 2-propynoates mainly give trans-beta, gamma-disubstituted gamma-lactones, and substituted 2-propynoates afford cis-beta,gamma-disubstituted gamma-lactones. Further elaborations of the halogen atoms and the synthesis of A-factor using this method are exemplified.
  • A palladium-catalyzed construction of enantiomerically pure α-methylene-γ-butyrolactones. Enantiospecific synthesis of both enantiomers of methylenolactocin
    作者:Guoxin Zhu、Xiyan Lu
    DOI:10.1016/0957-4166(95)00096-8
    日期:1995.4
    Optically active β,γ-disubstituted-α-methylene-γ-butyrolactones were synthesized by palladium(II)-catalyzed cyclization reactions of homochiral allylic 2-alkynoates. The reaction was applied to the total synthesis of methylenolactocin in both enantiomeric forms.
