  L-脯氨酸衍生物作为手性转移剂在羧酸对映体识别中的应用

  摘要：

  四脯氨酸衍生的手性受体5，6，7，8分别容易地合成从开始大号脯氨酸。手性受体的对映体识别能力用一系列羧酸按11 H NMR光谱。分别通过Job图和非线性最小二乘拟合法确定了手性化合物与客体分子的每个对映体的摩尔比和缔合常数。作业图表明主机与所有来宾形成1：1即时复合体。受体对外消旋客体的对映体表现出不同的手性识别能力。在这项研究中使用的手性受体中，脯氨酰胺6被认为是最好的手性转移试剂，对于确定手性羧酸的对映异构体过量有效。手性，2011年。©2011 Wiley‐Liss，Inc.。

  Chiral Lewis Acid Controlled Synthesis (CLAC Synthesis): Chiral Lewis Acids Influence the Reaction Course in Asymmetric Aldol Reactions for the Synthesis of Enantiomeric Dihydroxythioester Derivatives in the Presence of Chiral Diamines Derived from L-Proline

  摘要：

  AbstractBoth enantiomers of 2,3‐dihy‐droxythioester derivatives were prepared with almost perfect stereochemical control by chiral Lewis acid controlled synthesis (CLAC synthesis). CLAC synthesis means synthesis of all individual diastereomers or enantiomers from the same starting materials by designing chiral Lewis acids. For example, (Z)‐1‐ethyl‐thio‐1‐(trimethylsiloxy)‐2‐(tert‐butyldi‐methylsiloxy)ethene (1) reacted with aldehydes in the presence of chiral tin(II) Lewis acids using (S)‐1‐methyl‐2‐[(isoin‐dolinyl)methyl]pyrrolidine (4) and (S)‐1‐methyl‐2‐[(indolinyl)methyl]pyrrolidine (5) to afford enantiomeric dihydroxy‐thioester derivatives. Chiral diamines 4 and 5, which were readily prepared from L‐proline, differ only in the fusion point of the benzene ring connected to the pyrrolidine moiety. The unique selectivities were ascribed to the conformational difference between the chiral tin(II) Lewis acids of chiral diamines 4 and 5, and the function of chiral sources for obtaining high selectivities has also been clarified.
