  An efficient method for the synthesis of 2,3-dichloro-5-substituted (Cl, CF3, alkyl) pyridines starting from the 1:1 adducts of the copper-catalysed addition of chloral or the corresponding 2,2-dichloroaldehydes to acrylonitrile is presented. Proper choice of experimental conditions allows the preparation of in a one-pot process. Similarly, the CuCl-catalysed reaction of methyl itaconate with several

  一种有效的方法，从铜催化的氯醛或相应的2,2-二氯醛向丙烯腈的加成反应的1：1加合物开始，合成2,3-二氯-5-取代的（Cl，CF 3，烷基）吡啶被表达。正确选择实验条件可以在一锅法中进行制备。类似地，衣康酸甲酯与几种三氯甲基化合物R-CCl 3的CuCl催化反应通过脱卤作用和随后的1：1加合物的热闭环反应，得到了6-R-取代的2-吡喃酮衍生物。新型亲电子2-吡喃酮进行[4 + 2]-环加成反应，并与许多烯烃和乙炔进行逆电子需求，从而可以从简单的氟利昂衍生物（1,1,1-三氯-2,2,2-三氟乙烷）区域选择性转移三氟甲基变成更复杂的有机分子。最后，三氯乙酰氯与丙烯酸甲酯的1：1加合物可以非常方便地合成焦谷氨酸和脯氨酸的新型N-取代衍生物。

  日期：1992.1

  variety of new 3-(1-haloalkyl)oxaziridines was synthesized by oxidation of α-chloro-, α-bromo-, α,α-dichloro-, α,α-dibromo- and α,α,α-trichloroaldimines with meta-chloroperbenzoic acid. Attempts to induce dehydrohalogenation into the elusive methyleneoxaziridines were unsuccessful. However, presumptive evidence is presented that 2-t-butyl-3-(trichloromethyl)oxaziridine is dehydrochlorinated into a transient

  日期：2010.2.22

  Previously unexplored enantiopure zwitterionic ammonium dienolates have been utilized in this work as reactive intermediates that act as diene components in hetero‐Diels–Alder reactions (HDAs) with aldehydes to produce optically active δ‐lactones, subunits of numerous bioactive products. The dienolates were generated in situ from E/Z mixtures of α,β‐unsaturated acid chlorides by use of a nucleophilic

  以前未经探索的对映纯两性离子二烯酸铵已被用作反应性中间体，在醛与异狄尔斯-阿尔德反应（HDA）中与二烯一起充当醛，以产生光学活性的δ-内酯，这是许多生物活性产物的亚基。通过使用亲核性奎尼丁衍生物和Sn（OTf）2作为助催化剂，从α，β-不饱和酰氯的E / Z混合物中原位生成二烯酸酯。后者组分不直接与醛一起参与环加成步骤，而只是促进了反应性二烯酸酯类物质的形成。通过使用由Er（OTf）3形成的络合物，大大提高了环加成反应的范围。以及一个简单的市售去甲肾上腺素衍生的配体，该配体可耐受多种芳香族和杂芳香族醛，以协同作用于双官能路易斯酸/路易斯碱催化反应，从而提供具有出色对映选择性的α，β-不饱和δ-内酯。机理研究证实了两种催化体系均生成了二烯酸酯中间体。活性Er III络合物很可能是单体物质。有趣的是，所有镧系元素都可以催化标题反应，但是在产率和对映选择性方面的效率直接取决于Ln III离子的半径。同样，假镧系元素Sc
• Mechanistically Guided Design of an Efficient and Enantioselective Aminocatalytic α-Chlorination of Aldehydes
  作者：George Hutchinson、Carla Alamillo-Ferrer、Jordi Burés

  DOI：10.1021/jacs.1c02997

  日期：2021.5.12

  The enantioselective aminocatalytic α-chlorination of aldehydes is a challenging reaction because of its tendency to proceed through neutral intermediates in unselective pathways. Herein we report the rational shift to a highly selective reaction pathway involving charged intermediates using hexafluoroisopropanol as solvent. This change in mechanism has enabled us to match and improve upon the yields

  醛的对映选择性氨基催化 α-氯化是一个具有挑战性的反应，因为它倾向于在非选择性途径中通过中性中间体进行。在这里，我们报告了向高选择性反应途径的合理转变，该反应途径涉及使用六氟异丙醇作为溶剂的带电中间体。这种机制的变化使我们能够匹配和改进先前方法显示的产率和对映选择性，同时使用更便宜的氨基催化剂和氯化剂，催化剂用量减少 80-95%，温度方便，反应时间更短。
