  在硫化物的铜催化的不对称氧化的立体和电子效应调查

  摘要：

  已经研究了在铜催化的芳基苄基，芳基烷基和烷基苄基硫化物的不对称氧化中的立体效应和电子效应。直接连接到硫上的芳基的存在对于提供具有高对映选择性的亚砜是必不可少的，2-萘基苄基亚砜具有高达97％ee的电子，这是迄今为止铜催化的不对称亚砜氧化所达到的最高对映选择性。与此相反，苄基取代基可以通过在空间上可比基团与对映选择性上没有影响取代。的取代的芳基苄基硫化物铜 - 介导的氧化导致显示在相当或更低的对映选择性，以与未取代的苄基苯基硫醚获得的那些适度立体和电子效应。

  日期：2012.4.6

  Copper-catalyzed asymmetric sulfoxidation of aryl benzyl and aryl alkyl sulfides, using aqueous hydrogen peroxide as the oxidant, has been investigated. A relationship between the steric effects of the sulfide substituents and the enantioselectivity of the oxidation has been observed, with up to 93% ee for 2-naphthylmethyl phenyl sulfoxide, in modest yield in this instance (up to 30%). The influence

  研究了使用过氧化氢水溶液作为氧化剂的铜催化的芳基苄基和芳基烷基硫化物的不对称硫氧化反应。已经观察到硫化物取代基的空间效应与氧化的对映选择性之间的关系，其中2-萘甲基甲基苯基亚砜的ee高达93％，在这种情况下产率适中（高达30％）。检查了溶剂和配体结构变化的影响，然后使用优化的条件氧化了许多芳基烷基和芳基苄基硫化物，在大多数情况下以极好的收率（高达92％）产生亚砜，并且在室温下具有良好的对映体纯度。某些情况下（高达ee的84％）。

  symmetric – i.e. prochiral – diheteroaryl sulfoxides. The latter were treated with a 0.5- or 1.2-fold molar amount of 5:4 mixtures of dilithium (S)-BINOLate and diisobutylmagnesium. This allowed five asymmetric sulfoxide/magnesium exchange reactions to occur. They delivered asymmetric sulfoxides in up to 77 % yield and with up to 88 % ee. Surprisingly, four related diheteroaryl sulfoxides, bis(2-pyridyl)

  5 元环杂环被α-锂化或α-镁化，以便它们攻击SOCl2 或SO(OMe)2，形成对称的——即前手性——二杂芳基亚砜。后者用0.5-或1.2-倍摩尔量的5:4二锂(S)-BINOLate和二异丁基镁的混合物处理。这允许发生五个不对称的亚砜/镁交换反应。他们以高达 77% 的产率和高达 88% 的 ee 提供不对称亚砜。令人惊讶的是，四种相关的二杂芳基亚砜、双（2-吡啶基）亚砜和双（3-吡啶基）亚砜不适合这种交换，而是分解了。

  enantioselective sulfoxidation of various sulfides has been achieved by a N,N'-dioxide-iron(iii) complex with 35% aq. H2O2 as the oxidant. The utility of the current method was demonstrated by asymmetric gram-scale synthesis of drug molecule (R)-modafinil. Moreover, a possible working mode was provided to elucidate the chiral induction.

• Symmetric Diarylsulfoxides as Asymmetric Sulfinylating Reagents for Dialkylmagnesium Compounds
  作者：Simon Ruppenthal、Reinhard Brückner

  日期：2015.1.16

  dilithium salt of (S)-BINOL was added as a promotor. Alkyl aryl sulfoxides resulted in up to quantitative yield and with up to 97% ee. This demonstrates the feasibility of asymmetric sulfinylations by achiral sulfinylating agents (from the perspective of Alkyl2Mg) as well as the feasibility of asymmetric sulfoxide–magnesium exchanges (from the perspective of Ar2SO).

  在-78°C下，当添加1.5当量的（S）-BINOL二锂盐作为促进剂时，伯二烷基镁化合物与二芳基亚砜反应。烷基芳基亚砜导致定量产率最高，ee高达97％。这证明了通过非手性亚磺化剂进行不对称亚磺酰基化的可行性（从烷基2 Mg的角度来看），以及不对称亚砜与镁交换的可行性（从Ar 2 SO角度来看）。
• Enantioselective inclusion of chiral alkyl aryl sulfoxides in a supramolecular helical channel consisting of an enantiopure 1,2-amino alcohol and an achiral carboxylic acid

  日期：2008.2

  The enantio selective clathrate formation of alkyl aryl sulfoxides 4 was achieved with dissymmetric one-dimensional helical channels created in two-component hosts consisting of (1R,2S)-2-amino-1,2-diphenylethanol 1 and an achiral carboxylic acid, p-tert-butylbenzoic acid 2, or 2-anthraquinonecarboxylic acid 3. X-ray crystallographic analyses showed that the host framework (1R,2S)-1.3 in the single crystal of a clathrate with methyl p-methylphenyl sulfoxide 4n [(1R,2S)-1.3.4n (single)] maintained a supramolecular helical array as those of the solvent-included single crystals (1R,2S)-1.3-EtOH(single) and (1R,2S)-1-3-H2O.THF(single), while the guest 4n molecules were highly disordered. Moreover, the X-ray powder diffraction pattern of (1R,2S)-1-3-4n(clathrate) obtained through the clathrate formation demonstrated that the molecular arrangements of (1R,2S)-1, 3, and 4n were not the same as those which appeared in (1R,2S)-1.3.4n(single); the channel was enlarged. These results are consistently explained by assuming the dynamic motion of the framework (1R,2S)-1-3 to achieve widely applicable clathrate formation. (c) 2007 Elsevier Ltd. All rights reserved.
