    通过 Retro-Oxa-Michael 加成实现的动态动力学分辨率对 2,3-二取代黄烷酮进行不对称转移氢化:三个连续立体中心的构建
    摘要:
    通过动态动力学拆分和逆氧-迈克尔加成的结合,开发了一种钌催化的 2,3-二取代黄烷酮的不对称转移氢化,用于在碱性条件下构建三个连续的立体中心,从而使手性黄烷醇具有优异的对映选择性和非对映选择性。该反应通过碱催化的逆氧-迈克尔加成同时消旋两个立体中心与高度对映选择性的酮转移氢化步骤进行。在不损失活性和对映选择性的情况下,可以在克级实现不对称转移氢化。

    A concise total synthesis of biologically active frutinones via tributylphosphine-catalyzed tandem acyl transfer-cyclization
    摘要:
    A concise and step-economical total synthesis of biologically active frutinones has been achieved. Tributylphosphine (PBu3) efficiently induced the tandem acyl transfer-cyclization of carbonates 5 to afford 3-methoxycarbonylflavone derivatives 4 in excellent yields. Finally, concomitant deprotection and lactonization under acidic conditions furnished the desired frutinones A (1a), B (1b), and the proposed structure of frutinone C (1c). (C) 2014 Elsevier Ltd.

    With the rapid development of biomimetic asymmetric reduction, the demand for efficient chiral and regenerable NAD(P)H models is growing rapidly. Herein, a new class of [2.2]paracyclophane-based chiral and regenerable NAD(P)H models (CYNAMs) was designed and synthesized. The first enantioselective biomimetic reduction of tetrasubstituted alkene flavonoids has been successfully realized through enzyme-like
