  • Preparation of enantiopure butane-2,3-diacetals of glycolic acid and alkylation reactions leading to α-hydroxyacid and amide derivatives
    作者:Steven V. Ley、Elena Diez、Darren J. Dixon、Richard T. Guy、Patrick Michel、Gillian L. Nattrass、Tom D. Sheppard
    DOI:10.1039/b412788a
    日期:——
    The preparation of butane-2,3-diacetal protected glycolic acid and related systems is described together with highly selective alkylation reactions of (R,R) and (S,S) butanediacetal protected glycolic acid. These compounds are readily deprotected to give enantiopure alpha-hydroxyacids, alpha-hydroxyesters or alpha-hydroxyamides by suitable choice of conditions.
    描述了由2,3-二缩醛丁烷保护的乙醇酸的制备方法和相关系统,以及(R,R)和(S,S)丁二缩醛保护的乙醇酸的高度选择性烷基化反应。这些化合物可容易地脱保护,得到对映体纯的α-羟基酸,由条件适当选择的α-羟基酯或α-羟基酰胺。
  • Highly Diastereoselective Lithium Enolate Aldol Reactions of Butane-2,3-diacetal Desymmetrized Glycolic Acid and Deprotection to Enantiopure <i>anti</i>-2,3-Dihydroxy Esters
    作者:Darren J. Dixon、Steven V. Ley、Alessandra Polara、Tom Sheppard
    DOI:10.1021/ol016707n
    日期:2001.11.1
    [reaction--see text] The butane-2,3-diacetal (BDA) desymmetrized glycolic acid building block 1 undergoes efficient and highly diastereoselective lithium enolate aldol reactions with both aromatic and aliphatic aldehydes to afford, after an acidic methanolysis deprotection step, the enantiopure anti-2,3-dihydroxy esters in good yield.
    [反应-参见文本]异丁烷2,3-二缩醛(BDA)乙醇酸结构单元1与芳香族和脂肪族醛进行高效且高度非对映选择性的烯醇酸锂醛醇缩醛反应,从而在酸性甲醇分解脱保护步骤后得到对映体纯的抗2,3-二羟基酯,收率良好。
  • Flow Ozonolysis Using a Semipermeable Teflon AF-2400 Membrane To Effect Gas−Liquid Contact
    作者:Matthew O’Brien、Ian R. Baxendale、Steven V. Ley
    DOI:10.1021/ol100322t
    日期:2010.4.2
    A flow-through chemistry apparatus has been developed which allows gases and liquids to contact via a semipermeable Teflon AF-2400 membrane. In this preliminary investigation, the concept was proven by application to ozonolysis of a series of alkenes.
  • Synthesis of Enantiomers ofButane-1,2-diacetal-Protected Glyceraldehyde and of (<i>R</i>,<i>R</i>)-Butane-1,2-diacetal-ProtectedGlycolic Acid
    作者:Steven V. Ley、Patrick Michel
    DOI:10.1055/s-2003-40519
    日期:——
    A convenient and scalable synthesis of enantiomers of butane-2,3-diacetal-protected glyceraldehyde was accomplished from D-mannitol and L-ascorbic acid, respectively. The R-aldehyde was additionally converted to the (R,R)-butane-2,3-diacetal glycolic acid building block 1.

  • The continuous flow synthesis of butane-2,3-diacetal protected building blocks using microreactors
    作者:Catherine F. Carter、Ian R. Baxendale、John B. J. Pavey、Steven V. Ley
    DOI:10.1039/b924309g
    日期:——
    The continuous flow synthesis of butane-2,3-diacetal protected derivatives has been achieved using commercially available flow chemistry microreactors in concert with solid supported reagents and scavengers to provide in-line purification systems. The BDA protected products are all obtained in superior yield to the corresponding batch processes.
