  • Direct Synthesis of β,γ-Unsaturated α-Keto Esters from Aldehydes and Pyruvates
    作者:John Mansaray、Jiarui Sun、Shisheng Huang、Weijun Yao

    methods to synthesize β,γ-unsaturated α-keto esters directly from aldehydes and pyruvates promoted by BF3•Et2O in the presence of Ac2O or by Ti(OEt)4 under mild conditions. A variety of aromatic aldehydes was tolerated to afford the desired products in moderate to excellent yield. Moreover, aliphatic aldehydes and Isatin were also employed to give the γ-alkyl β,γ-unsaturated α-keto esters in moderate yield
    在这里,我们描述了两种实用的方法,在温和条件下,在 Ac2O 或 Ti(OEt)4 存在下,由 BF3•Et2O 促进的醛和丙酮酸盐直接合成 β,γ-不饱和 α-酮酯。可以耐受各种芳香醛,以中等至极好的收率提供所需的产品。此外,脂肪醛和靛红也被用于通过使用 Ti(OEt)4 系统以中等产率得到 γ-烷基 β,γ-不饱和 α-酮酯。

  • Deracemisation of aryl substituted α-hydroxy esters using Candida parapsilosis ATCC 7330: effect of substrate structure and mechanism
    作者:B. Baskar、N.G. Pandian、K. Priya、Anju Chadha
    DOI:10.1016/j.tet.2005.09.104
    日期:2005.12
    Candida parapsilosis ATCC 7330 was found to be an efficient biocatalyst for the deracemisation of aryl alpha-hydroxy esters (65-85% yield and 90-99% ee). A variety of aryl and aryl substituted alpha-hydroxy esters were synthesized to reflect steric and electronic effects on biocatalytic deracemisation. The mechanism of this biocatalytic deracemisation was found to be stereoinversion. (c) 2005 Elsevier Ltd. All rights reserved.
