    Cu催化动态动力学不对称烯丙基烷基化中的非稳定亲核试剂
    摘要:
    形成不对称碳-碳键的新反应的发展使化学家能够合成范围广泛的重要含碳分子,包括药剂、香料和聚合物。大多数获得对映异构体富集分子的策略依赖于从前手性底物生成新的立体中心或解析对映异构体的外消旋混合物。另一种策略——动态动力学不对称转化——涉及将外消旋原料转化为单一对映异构体产品,最大产率超过 50%。在钯催化的不对称烯丙基烷基化反应中使用稳定的亲核试剂(pKa < 25,其中 Ka 是酸解离常数)已被证明在这些过程中非常通用。反过来,在此类反应中使用不稳定的亲核试剂是困难的,并且仍然是一个关键挑战。在这里,我们报告了使用外消旋底物和烷基亲核试剂的铜催化动态动力学不对称转化。这些亲核试剂的 pKa ≥ 50,比此类转化中通常使用的亲核试剂碱性高 25 个数量级以上。有机金属试剂是通过氢金属化从烯烃原位生成的,并在温和的反应条件下得到高度对映体富集的产物。该方法用于合成具有抗结核和麻风活性的天然产

    The present invention provides processes for the production of chiral compounds in a stereoisomeric excess, the processes comprising: (i) contacting a first compound comprising an alkene or alkyne bond with a hydrometallating agent, wherein the first compound and the hydrometallating agent are contacted under conditions such that the first compound is hydrometallated by said hydrometallating agent; and (ii) contacting the hydrometallated first compound with a second compound comprising an allylic group, wherein the hydrometallated first compound and the second compound are contacted under conditions such that they undergo an asymmetric allylic alkylation reaction in which a carbon atom of the hydrometallated first compound binds to a carbon atom of said allylic group, forming a stereoisomeric excess of a compound having a chiral centre in an allylic position, said chiral centre being located at the carbon atom bound by said first compound, wherein said asymmetric allylic alkylation reaction is performed in the presence of a metal catalyst comprising a chiral ligand. In particular, the present invention provides processes for the production of a stereoisomeric excess of a compound of the formula (IA), (IB), (IA') or (IB') as defined herein.

    Methods for modifying therapeutic agents such as therapeutic biomolecules, such as proteins for improved oral, rectal or transmucosal delivery, as well as compositions made using such methods and methods of administering such compositions to a subject, are disclosed. Specifically, the therapeutic agents are conjugated to hyperbranched polymers (HBPs), such as hyperbranched polyglycerol (HPG). When such conjugates are administered orally to a subject, the HBP protects the therapeutic agent from the acid environment of the stomach and protease attack in the gastro-intestinal tract, while facilitating the absorption of the therapeutic agent in the higher pH environment of the intestines. The methods and compositions are useful for the improved administration of a variety of therapeutic agents to a subject.
