    [2 + 2] Cycloaddition of chlorosulfonyl isocyanate to chiral alkyl vinyl ethers bearing a sterogenic center in the alkyl part of the ether afford the corresponding azetidin-2-ones with relatively good asymmetric induction in certain cases. Reactions were shown to depend on steric requirements of the ligands at the stereogenic center. The model that rationalizes the stereochemical outcome is based on

  • Phosphane ligands with two binding sites of differing hardness for enantioselective Grignard cross coupling
    作者:Andreas Terfort、Henri Brunner
    DOI:10.1039/p19960001467
    日期:——
    A series of new, chiral phosphanes is presented, individual members of which were designed to serve as ligands in transition-metal mediated asymmetric Grignard cross coupling reactions. These ligands are characterized by a side chain containing one or two oxygen atoms with the capacity to act as binding sites for the incoming Grignard reagent. A number of structural parameters for the compounds was varied to learn about the reaction mechanism. Most of the ligands were tested in two cross coupling reactions, the formation of 3-phenylbut-1-ene and of 2,2′-dimethyl-1,1′-binaphthyl, respectively. Although both systems gave modest enantiomeric excesses it was not possible to make a comparison of their respective abilities.
    一系列新型手性膦被呈现出来,其中每个成员都被设计为在过渡属介导的不对称Grignard交叉偶联反应中作为配体。这些配体的特点是具有含一个或两个氧原子的侧链,它们具备作为进入的Grignard试剂结合位点的能力。研究中改变了许多化合物的结构参数以深入了解反应机理。多数配体在两种交叉偶联反应中进行了测试,分别用于生成3-苯基丁-1-烯和2,2′-二甲基-1,1′-联。虽然这两个系统都获得了适度的对映体过量,但无法对其各自的能力进行比较。

    results of the biological tests indicate that analogs with a methyl group alpha to the phosphate moiety (11c,d) exhibit a marked degree of stereoselectivity with regard to their anti-HIV activity. Also, replacement of the long alkyl chain with aromatic groups in the oxyalkyl ether phospholipid-AZT conjugates leads to substantially more potent compounds (11e-g) with an anti-HIV activity comparable to that
