  A One-Pot Process for the Enantioselective Synthesis of Amines via Reductive Amination under Transfer Hydrogenation Conditions

  摘要：

  Cyclic amines may be prepared via a sequence of deprotection followed by intramolecular reductive amination of t-Boc-protected amino ketones under asymmetric transfer hydrogenation conditions. In cases where the corresponding imine reaction proceeds with high enantioselectivity, this is reflected in the one-step process.

• Synthesis of Tetrazole-Derived Organocatalysts via Azido-Ugi Reaction with Cyclic Ketimines
  作者：Olga I. Shmatova、Valentine G. Nenajdenko

  DOI：10.1021/jo401428q

  日期：2013.9.20

  A new route to tetrazole-derived cyclic amines based on the TMSN3-modified Ugi reaction with 2-substituted cyclic imines was elaborated. The reaction allows the direct preparation of five-, six-, and seven-membered cyclic amines substituted with a tetrazole ring, which are important types of organocatalysts. The scope and limitations of this method are discussed. In the case of the Ugi reaction with

  基于TMSN 3的四唑衍生环胺的新途径阐述了用2-取代的环状亚胺进行的修饰的Ugi反应。该反应允许直接制备被四唑环取代的五元，六元和七元环胺，这是重要的有机催化剂类型。讨论了该方法的范围和局限性。在Ugi与苄基异氰化物反应的情况下，N-取代的四唑可以在催化氢化条件下容易地脱苄基，以定量收率形成NH-四唑。证明了四唑衍生的环胺的两种对映体都可以通过酒石酸拆分而制备，从而引发了一种简单的手性衍生物路线。在胺化反应中，将获得的手性四唑之一有效地用作有机催化剂。

  The six‐component azido‐Ugi reaction with 2‐substituted 5–7‐membered imines leads to mono‐ or bis‐tetrazole derivatives depending on the starting imines. The reaction is very general regarding isocyanide structure and enables preparation of 1,5‐disubstituted bis‐tetrazole derivatives connected with 5–7‐membered cyclic amine fragments. Subsequent catalytic debenzylation provides the corresponding 1H‐tetrazoles

  与2个取代的5-7元亚胺形成的六组分叠氮基-Ugi反应取决于起始的亚胺，生成单或双四唑衍生物。关于异氰酸酯的结构，该反应非常笼统，可制备与5-7元环胺片段连接的1,5-二取代双-四唑衍生物。随后的催化脱苄基作用提供了相应的1H-四唑。

  enantiomerically pure chiral amines continues to expand, few existing methods provide access to secondary amines. To address this shortcoming, we have over-expressed the gene for an (R)-imine reductase [(R)-IRED] from Streptomyces sp. GF3587 in Escherichia coli to create a recombinant whole-cell biocatalyst for the asymmetric reduction of prochiral imines. The (R)-IRED was screened against a panel of cyclic imines

  尽管可用于合成对映体纯的手性胺的生物催化剂的范围不断扩大，但现有的方法很少能提供仲胺的途径。为了解决这个缺点，我们过量表达了链霉菌属（Streptomyces sp。）的（R）-亚胺还原酶[（R）-IRED]的基因。GF3587在大肠杆菌中创建重组全细胞生物催化剂，用于不对称还原前手性亚胺。针对一组环状亚胺和两个亚胺离子筛选了（R）-IRED，结果显示该催化剂具有较高的催化活性和对映选择性。从亚胺前体的制备规模的生物碱（R）-亚氨酸的合成规模（90％收率； 99％ee）以克为单位进行。酶活性位点的同源模型，基于来自链霉菌的紧密相关的（R）-IRED的结构，

  Treatment of 5-, 6- and 7-membered cyclic ketimines bearing alkyl or aryl group with m-chloroperbenzoic acid proceeds as C=N epoxidation and affords bicyclic oxaziridines in good yields, whose subsequent rearrangement gives nitrones.

  A general route to alpha‐substituted cyclic amino acids was elaborated. The approach is based on Strecker reaction with cyclic ketimines. The series of 5–7 membered amino nitriles having different substituents were prepared. Synthesis of alpha‐substituted prolines and their amides was elaborated starting from the corresponding 5‐membered ketimines
