  Preparation of optically active ortho-chloro- and ortho-bromophenyl sulfoxides

  摘要：

  The preparation of the diastereomerically pure menthyl (S)-2-chloro- and (S)-2-bromophenyl sulfinates by esterification of the corresponding sulfinic acids with ( 1 R,2S,5R)- (-)-menthol and recrystallization/epimerization is reported. The two sulfinates have been converted into enantiomerically pure aryl, vinyl and alkyl sulfoxides by reaction with organomagnesium reagents. These sulfoxides are useful chiral auxiliaries to control the stereochemical outcome of radical reactions. (C) 1999 Elsevier Science Ltd. Ail rights reserved.

• Investigations on the Iron-Catalyzed Asymmetric Sulfide Oxidation
  作者：Julien Legros、Carsten Bolm

  DOI：10.1002/chem.200400857

  日期：2005.2.4

  The development of an enantioselective sulfide oxidation involving a chiral iron catalyst and aqueous hydrogen peroxide as oxidant is described. In the presence of a simple carboxylic acid, or a carboxylate salt, the reaction affords sulfoxides with remarkable enantioselectivities (up to 96 % ee) in moderate to good yields. The influence of the structure of the additive on the reaction outcome is reported

  The asymmetric oxidation of sulfides to chiral sulfoxides with hydrogen peroxide in good yield and high enantioselectivity has been catalyzed very effectively by chiral vanadium−salan [N,N‘-alkyl bis(salicylamine)] complex. The salan ligand shows results superior in terms of reactivity and enantioselectivity to those of salen [N,N‘-alkylene bis(salicylideneimine)] analogue, and provides the sulfoxide

  frontier in the development of chiral stationary phases for chromatographic enantioseparation involves homochiral metal–organic frameworks (MOFs). Using enantiopure (R)-2,2′-dihydroxy-1,1′-binaphthalene-6,6′-dicarboxylic acid as a starting material, we prepared three homochiral MOFs that were further used as chiral stationary phases for high-performance liquid chromatography to separate the enantiomers

• Chiral Ionic Liquids as Stationary Phases in Gas Chromatography
  作者：Jie Ding、Thomas Welton、Daniel W. Armstrong

  DOI：10.1021/ac049144c

  日期：2004.11.1

  Recently, it has been found that room-temperature ionic liquids can be used as stable, unusual selectivity stationary phases. They show “dual nature” properties, in that they separate nonpolar compounds as if they are nonpolar stationary phases and separate polar compounds as if they are polar stationary phases. Extending ionic liquids to the realm of chiral separations can be done in two ways:  (1) a chiral selector can be dissolved in an achiral ionic liquid, or (2) the ionic liquid itself can be chiral. There is a single precedent for the first approach, but nothing has been reported for the second approach. In this work, we present the first enantiomeric separations using chiral ionic liquid stationary phases in gas chromatography. Compounds that have been separated using these ionic liquid chiral selectors include alcohols, diols, sulfoxides, epoxides, and acetylated amines. Because of the synthetic nature of these chiral selectors, the configuration of the stereogenic center can be controlled and altered for mechanistic studies and reversing enantiomeric retention.

  最近发现，常温离子液体可以用作稳定且具有特殊选择性的固定相。它们表现出“二元性”特性，既能像非极性固定相一样分离非极性化合物，又能像极性固定相一样分离极性化合物。将离子液体扩展到手性分离领域有两种方法：（1）将手性选择剂溶解在非手性离子液体中，或（2）离子液体本身具有手性。第一种方法已有唯一的先例，而第二种方法尚未有报道。在这项工作中，我们展示了首次使用手性离子液体固定相在气相色谱中进行的对映体分离。使用这些离子液体手性选择剂分离的化合物包括醇、二醇、亚磺酰氧、环氧化物和乙酰胺。由于这些手性选择剂的合成特性，立体中心的构型可以在机制研究和反转对映体保留过程中进行控制和改变。
