    甲基丙烯酸、Tiglic 和当归酸的酯和酰胺的不对称二羟基化:Sharpless 助记符也不例外!
    摘要:
    关于当归酸异丁酯的 Sharpless 不对称二羟基化 (SAD) 面部选择性的文献发现是矛盾的,部分与 Sharpless 助记符相冲突。我们系统地筛选了当归、tiglic 和甲基丙烯酸的酯和酰胺的 SAD。在 15 个反应中的 14 个反应中出现了对映体控制,在 tiglic acid 的 Weinreb 酰胺的 ee 达到 99% 时达到顶峰。所有非外消旋产物的绝对构型都是通过(立体)化学相关性建立的。无一例外,它们都符合 Sharpless 助记符。

  • Synthesis of a new conformationally constrained glycoamino acid building block
    作者:Alberto Avenoza、Jesús M. Peregrina、Emilio San Martı́n
    DOI:10.1016/s0040-4039(03)01586-7
    日期:2003.8
    The synthesis of a suitably protected β-d-glucopyranosyl-(S)-α-methylserine derivative—a new conformationally constrained glycosylated quaternary amino acid analogue of β-d-glucopyranosyl-l-serine—is described. This compound can be used as an attractive building block for the synthesis of new, constrained glycopeptides.

  • An alternative approach to (S)- and (R)-2-methylglycidol O-benzyl ether derivatives
    作者:Alberto Avenoza、Carlos Cativiela、Jesús M. Peregrina、David Sucunza、Marı́a M. Zurbano
    DOI:10.1016/s0957-4166(01)00230-0
    日期:2001.6
    This report describes the gram scale synthesis of (S)- and (R)-2,2,4-trimethyl-4-(hydroxymethyl)-1,3-dioxolanes using the Sharpless asymmetric dihydroxylation (AD) of the Weinreb amide of 2-methyl-2-propenoic acid. The 2-methylglycerol acetonides resultant from protection of the AD products were used as starting materials in the synthesis of O-benzyl ethers of the valuable C4-chiral building blocks (S)- and (X)-2-methylglycidol.

  • Preparation of 2(R) and 2(S) methyl-2-methylglycerates
    作者:Juan B. Rodríguez、Sanford P. Markey、Herman Ziffer
    DOI:10.1016/s0957-4166(00)86020-6
    日期:1993.1
    Optically pure samples of both enantiomers of methyl 2,3-dihydroxy-2-methylpropanoate were prepared by a chromatographic separation of their (-)-menthyl esters followed by hydrolysis and methylation. Their absolute stereochemistries were established by conversion into their 3-0-acetyl derivatives, compounds of established configuration. NMR and CG-MS methods of determining the optical purities of the diols are described.
  • Enantioselective synthesis of (S)- and (R)-α-methylserines: application to the synthesis of (S)- and (R)-N-Boc-N,O-isopropylidene-α-methylserinals
    作者:Alberto Avenoza、Carlos Cativiela、Francisco Corzana、Jesús M. Peregrina、David Sucunza、Marı́a M. Zurbano
    DOI:10.1016/s0957-4166(01)00159-8
    日期:2001.4
    This report describes the synthesis of enantiomerically pure (S)- and (R)-alpha -methylserines on a multigram scale, starting from the Weinreb amide of 2-methyl-2-propenoic acid and using a stereodivergent synthetic route that involves a Sharpless asymmetric dihydroxylation reaction. As a synthetic application of these quaternary alpha -amino acids, they were used as starting materials in the synthesis of the well-known valuable homochiral (S)- and (R)-N-Boc-N,O-isopropylidene-alpha -methylserinal building blocks.
