  日期：2019.9.6

  Cp*Ir complexes bearing a 2-picolinamide moiety serve as effective catalysts for the direct reductive amination of ketonic compounds to give primary amines under transfer hydrogenation conditions using ammonium formate as both the nitrogen and hydrogen source. The clean and operationally simple transformation proceeds with a substrate to catalyst molar ratio (S/C) of up to 20,000 at relatively low

  ortho-arylation of benzylamines followed by in situ lactamization. This cascade sequence is enabled by the use of 2-iodobenzoates, which facilitates C-H arylation from the free amine under conditions that typically require an improved directing group approach. This reaction is characterized by a broad substrate scope with good functional group tolerance. The need for an ester versus carboxylic acid-functionalized

  analogues were resolved on a CSP based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid. Fendiline was resolved quite well with the separation factor (α) of 1.25 and resolution (RS) of 1.55 when a mobile phase consisting of methanol-acetonitrile-trifluoroacetic acid-triethylamine at a ratio of 80/20/0.1/0.5 (v/v/v/v) was used. The comparison of the chromatographic behaviors for the resolution of fendiline

  芬迪林是一种有效的抗心绞痛治疗冠心病的药物，其十六种类似物在基于（+）-（18-crown-6）-2,3,11,12-四羧酸的CSP上拆分。当流动相由比例为80/20 / 0.1 / 0.5（v / v）的甲醇-乙腈-三氟乙酸-三乙胺组成的流动相时，芬迪林的分离度（α）为1.25，分离度（RS）为1.55 / v / v）。色谱分析法比较了芬迪林及其类似物的拆分行为，表明与芬迪林仲氨基键合的3,3-二苯丙基在手性识别中很重要，而苯基与苯丙氨酸之间的空间体积差异也很重要。芬迪林手性中心的甲基在手性识别中也很重要。

  stereoselective amination of (hetero)aromatic ketones using transaminases have been studied, such as temperature, pH, substrate concentration, cosolvent, and source and percentage of amino donor, to further optimize the production of enantiopure amines using both (S)- and (R)-selective biocatalysts from commercial suppliers. Interesting enantiopure amino building blocks have been obtained, overcoming some limitations

  Chiral resolutions of trifluoroacetyl‐derivatized 1‐phenylalkylamines with different type and position of substituent were investigated by capillary gas chromatography by using heptakis(2,3‐di‐O‐methyl‐6‐O‐tert‐butyldimethylsilyl)‐β‐cyclodextrin diluted in OV‐1701 as a chiral stationary phase. The influence of column temperature on retention and enantioselectivity was examined. All enantiomers of meta‐substituted
