• Synthesis of Isoquinoline Derivatives via Palladium‐Catalyzed C−H/C−N Bond Activation of <i>N</i> ‐Acyl Hydrazones with <i>α</i> ‐Substituted Vinyl Azides
  作者：Biao Nie、Wanqing Wu、Wei Zeng、Qingyun Ren、Ji Zhang、Yingjun Zhang、Huanfeng Jiang

  日期：2020.3.17

  A palladium‐catalyzed cyclization of N‐acetyl hydrazones with vinyl azides has been developed. Various substituted isoquinolines, including diverse fused isoquinolines can be prepared via this protocol in moderate to good yields. Mechanistic studies suggest that α‐substituted vinyl azide serves as an internal nitrogen source. Also, C−H bond activation and C−N bond cleavage have been realized using

• Dynamic Kinetic Resolution of Alcohols by Enantioselective Silylation Enabled by Two Orthogonal Transition‐Metal Catalysts
  作者：Jan Seliger、Martin Oestreich

  DOI：10.1002/anie.202010484

  日期：2021.1.4

  A nonenzymatic dynamic kinetic resolution of acyclic and cyclic benzylic alcohols is reported. The approach merges rapid transition‐metal‐catalyzed alcohol racemization and enantioselective Cu‐H‐catalyzed dehydrogenative Si‐O coupling of alcohols and hydrosilanes. The catalytic processes are orthogonal, and the racemization catalyst does not promote any background reactions such as the racemization

  报道了无环和环状苯甲醇的非酶动态动力学拆分。该方法融合了快速过渡金属催化的醇外消旋化和对映选择性 Cu-H 催化的醇和氢硅烷的脱氢 Si-O 偶联。催化过程是正交的，并且外消旋催化剂不会促进任何背景反应，例如甲硅烷基醚的外消旋及其非选择性形成。常用的钌半夹心配合物并不合适，但双功能钌钳形配合物完美地实现了这一目的。由此，可以高产率和良好的对映选择水平实现外消旋醇混合物的对映选择性硅烷化。
• Highly Enantioselective Transfer Hydrogenation of Prochiral Ketones Using Ru(II)-Chitosan Catalyst in Aqueous Media
  作者：György Szőllősi、Vanessza Judit Kolcsár

  DOI：10.1002/cctc.201801602

  日期：2019.1.23

  Unprecedentedly high enantioselectivities are obtained in the transfer hydrogenation of prochiral ketones catalyzed by a Ru complex formed in situ with chitosan chiral ligand. This biocompatible, biodegradable chiral polymer obtained from the natural chitin afforded good, up to 86 % enantioselectivities, in the aqueous‐phase transfer hydrogenation of acetophenone derivatives using HCOONa as hydrogen donor. Cyclic

  在与壳聚糖手性配体原位形成的Ru络合物催化的前手性酮的转移氢化中，获得了前所未有的高对映选择性。这种从天然几丁质中获得的生物相容性，可生物降解的手性聚合物，在使用HCOONa作为氢供体的苯乙酮衍生物的水相转移氢化中，提供了高达86％的良好对映选择性。环酮的对映选择性更高，超过90％，而在杂环酮的转移氢化中，进一步增加，最高可达97％。手性催化剂前体制备易地通过扫描电子显微镜，FT-中期和-far-IR光谱法检测。原位结构通过1 H NMR光谱和使用各种壳聚糖衍生物研究了形成的催化剂。结果表明，Ru预催化剂是通过氨基将生物聚合物与金属配位而形成的。加入氢供体后，该前体转化为水不溶性钌氢化物络合物。通过以高收率和光学纯度制备二十多种手性醇，验证了所开发方法的实用价值。在单次结晶后，将催化剂用于以克为单位获得光学纯的手性醇。

  日期：——

  The application of several 1-butyl-3-methylimidazolium (BMIM) salt ionic liquids as solvent in the α-methylenation of carbonyl compounds at room temperature is reported. The ionic liquid [BMIM][NTf2] gave a clean reaction in a short time and good yields of several α-methylene carbonyl compounds. This ionic liquid was reused without affecting the reaction rates or yields over seven runs.
