  Enantioselectivity switch controlled by N,N′-di- or N,N,N′,N′-tetra-substituted chiral thiophosphorodiamide ligands, structural relatives of thioureas, in catalytic additions of diethylzinc to aldehydes

  摘要：

  We have developed a series of new chiral thiophosphorodiamide ligands derived from (1R,2R)-(+)-1,2-diphenylethylenediamine, which are the structural relatives of thioureas. An investigation into their catalytic properties in asymmetric additions of diethylzinc to aldehydes has shown that N,N,N',N'-tetra-substituted chiral thiophosphorodiamides can give (R)-secondary alcohols with up to 98% yield and 98% ee, while N,N'-di-substituted chiral thiophosphorodiamides give (S)-secondary alcohols with up to 99% yield and 97% ee values. The enantioselectivity switch is highly efficient with a broad substrate scope. We have also proposed hypothetical reaction pathways, which result in an enantioselectivity switch.

  A novel chiral phosphine-urea bifunctional ligand has been developed for Cu-catalyzed asymmetric 1,3-dipolar cycloaddition of iminoesters with methacrylonitrile, a long-standing challenging substrate in asymmetric catalysis. Distortion-interaction energy analysis based on density functional theory (DFT) calculations reveals that the distortion energy plays an important role in the observed enantioselectivity

  已开发出一种新型手性膦-脲双功能配体，用于铜催化亚胺酯与甲基丙烯腈的不对称 1,3-偶极环加成反应，甲基丙烯腈是不对称催化中长期存在的挑战性底物。基于密度泛函理论 (DFT) 计算的畸变相互作用能量分析表明，畸变能量在观察到的对映选择性中起着重要作用，这可以归因于膦配体和偶极反应物之间的空间效应。DFT 计算还表明亲核加成是决定对映选择性的步骤，尿素部分和甲基丙烯腈之间的氢键有助于控制非对映选择性和对映选择性。通过结合金属催化和有机催化，出色的非对映选择性和对映选择性（高达 99：1 非对映体比率，99% 对映体过量）以及良好的产率。该催化剂体系可耐受亚氨基酯和丙烯腈的广泛取代模式，从而提供了获得一系列具有多达两个四元立体中心的高度取代的手性氰基吡咯烷的途径。合成效用通过具有关键腈药效团和全碳四元立体中心的抗肿瘤剂 ETP69 的对映选择性合成得到证明。

  A method for enantioselective direct α-amination reaction catalyzed by a sterically "frustrated" Lewis acid/Brønsted base complex is disclosed. Cooperative functioning of the Lewis acid and Brønsted base components gives rise to in situ enolate generation from monocarbonyl compounds. Subsequent reaction with hydrogen-bond activated dialkyl azodicarboxylates delivers α-aminocarbonyl compounds in high

  We have demonstrated that a validated QSAR (quantitative structure–activity relationship) model can be constructed between sterimol steric parameters of the N-substituents of chiral 1,2-amino-phosphoramide ligands and the enantiomeric ratios of alcohol products produced in the asymmetric additions of diethylzinc to acetophenone, which is powerful for predicting the steric effects of ligand substituents

The use of on-water condition turns on this otherwise extremely unreactive catalytic reaction as a result of the strengthened hydrogen bonds of water molecules near the hydrophobic reaction mixture. Furthermore, under on-water conditions, especially under biphasic microfluidic on-water conditions, access of bulk water into

  水中前手性碳负离子的催化对映选择性质子化是生物系统中的一种常见转化，但由于质子在水中异常快速的运动会导致不受控制的外消旋质子化，因此这超出了合成化学家的能力。在这里，我们展示了水的关键作用，它能够通过烯二醇中间体的对映选择性质子化进行半硫缩醛的高度对映选择性乙二醛酶 I 模拟催化异构化。由于疏水反应混合物附近的水分子的氢键增强，因此水上条件的使用开启了这种原本极其不活泼的催化反应。此外，在水上条件下，特别是在双相微流体水上条件下，
