    镍催化的带有氧离去基团的外消旋二级亲电体的对映选择性交叉偶联
    摘要:
    迄今为止,带有氧离去基团的烷基亲电试剂的有效镍催化对映选择性交叉偶联仅限于烯丙醇衍生物与格氏试剂的反应。在本通讯中,我们确定,在镍/pybox 催化剂的存在下,各种外消旋炔丙碳酸酯是与有机锌试剂不对称偶联的合适伙伴。该方法与一系列官能团兼容并使用市售催化剂组分。开发一种多功能的镍催化对映选择性交叉偶联过程,用于带有除卤化物以外的离去基团的亲电试剂,为这些反应的范围增加了一个重要的新维度。

  • Gold-Catalyzed Oxidative Reactions of Propargylic Carbonates Involving 1,2-Carbonate Migration: Stereoselective Synthesis of Functionalized Alkenes
    作者:Ning Sun、Ming Chen、Yuanhong Liu
    DOI:10.1021/jo500573s
    日期:2014.5.2
    A gold-catalyzed oxidative reaction of propargylic carbonates or acetates using 3,5-dichloropyridine as the oxidant has been developed. The reaction provides efficient access to α-functionalized-α,β-unsaturated ketones with excellent regio- and diastereocontrol via a regioselective attack of the N-oxide to the gold-activated alkyne followed by a 1,2-carbonate migration. In addition, the alkene products
    已经开发出使用3,5-二氯吡啶作为氧化剂的炔丙基碳酸酯乙酸酯的催化氧化反应。该反应可通过N氧化物对活化炔烃的区域选择性进攻,然后进行1,2-碳酸酯迁移,从而有效地获得具有出色的区域和非对映控制性的α-官能化的α,β-不饱和酮。另外,在碱性条件下,通过与丙酮的环缩合或环二聚,烯烃产物可以进一步转化为有价值的5-羟基环戊-2-烯酮。

    We report on a study of copper-catalyzed alkylation of internal allylic carbonates using functionalized alkyl and aryl Grignard reagents. The reactions exhibit good regioselectivity for either SN2 or SN2′ products, enabling the preparation of products with E-alkene selectivity. Density functional theory (DFT) calculations reveal the origins of the regioselectivity based on the different behaviors of
    我们报告了使用官能化烷基和芳基格氏试剂催化内烯丙基碳酸酯烷基化的研究。该反应对S N 2 或S N 2' 产物表现出良好的区域选择性,使得能够制备具有E-烯烃选择性的产物。密度泛函理论(DFT)计算揭示了基于同酸盐和异酸盐的不同行为的区域选择性的起源。

  • Studies on Pd(II)-Catalyzed Synthesis of (<i>Z</i>)-α-Haloalkylidene-β-lactones from Cyclocarbonylation of 2-Alkynols and the Subsequent Coupling Reactions
    作者:Shengming Ma、Bin Wu、Xuefeng Jiang、Shimin Zhao
    DOI:10.1021/jo0480038
    日期:2005.4.1
    A good regio- and stereoselectivity was observed for the PdCl2-catalyzed cyclocarbonylation of 2-alkynols with CuCl2 affording (Z)-alpha-chloroalkylidene-beta-lactons. The highly optically active (Z)-alpha-chloroalkylidene-beta-lactones could be easily prepared from the readily available optically active propargylic alcohols. The Pd(II)-catalyzed cyclocarbonylation of 2-alkynols with CuBr2 was also studied. Although the yields of (Z)-alpha-bromoalkylidene-beta-lactones were low, due to the relatively higher activity of the C-Br bond, the coupling reactions of (Z)-alpha-bromoalkylidene-beta-lactones were quite smooth to afford the corresponding products in high yields. A rationale for this reaction is discussed.
  • Mild and Efficient Synthesis of (<i>Z</i>)-α-Chloroalkylidene-β-lactones via the PdCl<sub>2</sub>-Catalyzed Cyclocarbonylation of 2-Alkynols
    作者:Shengming Ma、Bin Wu、Shimin Zhao
    DOI:10.1021/ol0357245
    日期:2003.11.1
    A mild and efficient methodology involving PdCl2-catalyzed cyclocarbonylation of 2-alkynols with CuCl2 for the synthesis of (Z)-alpha-chloroalkylidene-beta-lactones was developed. Using the readily available optically active propargylic alcohols allows convenient synthesis of the corresponding (Z)-alpha-chloroalkylidene-beta-lactones with high ee values. cis-Chloropalladation was observed as the major pathway, which is unique as compared to the reported data.
