  • A New Entry to Asymmetric Synthesis of Optically Active α,γ-Substituted γ-Butyrolactones, Using a Carbohydrate Derived Amide as Both a Chiral Auxiliary and a Proton Source
    作者:Ling-Lin Huang、Ming-Hua Xu、Guo-Qiang Lin

    日期:2005.1.1
    A new entry for the asymmetric synthesis of optically active α,γ-substituted γ-butyrolactones was developed by using a carbohydrate-derived amide as both a chiral auxiliary and a proton source. Unlike the previously reported examples, the chiral auxiliary employed in this reaction also successfully functioned as a protonating agent. Excellent asymmetric induction could be achieved by this dual stereoselective
    通过使用碳水化合物衍生的酰胺作为手性助剂和质子源,为光学活性α,γ-取代的γ-丁内酯的不对称合成开辟了一条新途径。与先前报道的实例不同,在该反应中使用的手性助剂也成功地用作质子化剂。在反应过程中通过这种双重立体选择性控制可以实现出色的不对称诱导。

  • Development of a New Reaction System for the Synthesis of Highly Optically Active α,γ-Substituted γ-Butyrolactones
    作者:Ming-Hua Xu、Wei Wang、Li-Jun Xia、Guo-Qiang Lin
    DOI:10.1021/jo0155153
    日期:2001.6.1
    A highly useful method for the synthesis of optically active alpha,gamma-substituted gamma-butyrolactones has been developed. The SmI(2)-induced reductive coupling of chiral 2-alkyl acrylates derived from isosorbide with ketones in the presence of (1S)-(-)-2,10-camphorsultam as a proton source give the chiral alpha,gamma-substituted gamma-butyrolactones in good yields and high enantiomeric purities
    已经开发了用于合成旋光的α,γ-取代的γ-丁内酯的非常有用的方法。SmI(2)诱导的异山梨醇与酮的手性2-烷基丙烯酸2-烷基酯的还原偶联,在存在(1S)-(-)-2,10-樟脑作为质子源的情况下,得到手性α,γ取代的γ -丁内酯,收率高,对映体纯度高(反式可高达99%ee,顺式可高达75%ee)。已经用各种酮研究了该反应系统,并且证明该系统对于反式α,γ-取代的γ-丁内酯是非常有效的。为了观察到优异的产品ee值,该系统中的手性助剂和受阻质子源都是必需的。

    日期:2000.7.1
    Using an easily accessible and inexpensive chiral auxiliary derived from isosorbide, optically active alpha,gamma-substituted gamma-butyrolactones were obtained in high enantiomeric purity (up to >99% ee for trans) by the SmI(2)-induced reductive coupling of chiral methacrylate 7 with ketones in the presence of (-)-sultam as a proton source.
    通过使用容易获得且廉价的衍生自异山梨醇的手性助剂,通过SmI(2)诱导的手性还原偶联以高对映体纯度(反式可达> 99%ee)获得了光学活性的α,γ-取代的γ-丁内酯(-)-sultam作为质子源存在时,带有酮的甲基丙烯酸7。
