  • Gosteli−Claisen Rearrangement: Substrate Synthesis, Simple Diastereoselectivity, and Kinetic Studies
    作者:Julia Rehbein、Sabine Leick、Martin Hiersemann

    日期:2009.2.20
    kinetic studies on the uncatalyzed [3,3]-sigmatropic rearrangement of 2-alkoxycarbonyl-substituted allyl vinyl ethers are reported. Apparently first reported by Gosteli in 1972, this variation of a Claisen rearrangement enjoyed a shadowy existence for three decades until its potential for the development of a catalytic asymmetric Claisen rearrangement was discovered. Inspired by this development, we have

    Progress in the catalytic asymmetric Claisen rearrangement of 2-alkoxycarbonyl-substituted allyl vinyl ether is reported. Application of a more Lewis acidic catalyst, [Cu(S,S)-t-Bu-box}](H2O)2(SbF6)2, afforded β-chiral α-keto ester with an enantiomeric excess up to 99%. We suggest a highly polarized transition state for the Lewis acid-catalyzed Claisen rearrangement in order to explain the experimental results

    and experimental study on the Claisen rearrangement of a 2-alkoxycarbonyl-substituted allyl vinyl ether in the presence of thioureas as potential noncovalent organocatalysts has been performed. DFT calculations employing different basis sets were utilized to predict a catalytic cycle for the thiourea-catalyzed Claisen rearrangement.

  • Integration of Catalysis and Analysis is the Key: Rapid and Precise Investigation of the Catalytic Asymmetric Gosteli–Claisen Rearrangement
    作者:Johannes Troendlin、Julia Rehbein、Martin Hiersemann、Oliver Trapp

    日期:2011.10.19
    The kinetics of the Cu-II(bisoxazoline)-catalyzed diastereoand enantioselective Gosteli-Claisen rearrangement of 2-alkoxycarbonyl-substituted allyl vinyl ethers has been investigated by enantioselective on-column reaction gas chromatography (ocRGC). Enantioselective ocRGC integrates (stereoselective) catalysis and enantioselective chromatography in a single microcapillary, which is installed in a GC-MS for direct analysis of conversion and selectivity. Thus, this technique allows direct differentiation of thermal and stereoselectively catalyzed reaction pathways and determination of activation parameters and selectivities of the individual reaction pathways starting from stereoisomeric reactants with high precision. Two modes of operation of enantioselective ocRGC are presented to investigate noncatalyzed, i.e., conversion of isopropyl-2-(allyloxy)but-2Z-enoate 1 to isopropyl-3R,S-methyl-2-oxy-hex-5-enoate (+/-)-2 and the [Cu(R,R)-Ph-box}](SbF6)(2)-catalyzed Gosteli-Claisen rearrangement, i.e., conversion of isopropyl-2-(but-2'E-en-1-yloxy)but-2Z-enoate (E,Z)-3 to isopropyl-3S,4S-dimethyl-2-oxy-hex-5-enoate 4b. Eyring activation parameters have been determined by temperature-dependent measurements: Uncatalyzed rearrangement of 1 to (+/-)-2 gives Delta G double dagger (298 K) = 114.1 +/- 0.2 kJ . mol(-1), Delta H double dagger = 101.1 +/- 1.9 kJ . mol(-1), and Delta S double dagger = -44 +/- 5 J . (K . mol)(-1), and catalyzed rearrangement of (E,Z)-3 to 4b gives Delta G double dagger (298 K) = 101.1 +/- 0.3 kJ . mol(-1), Delta H double dagger = 106.1 +/- 6.6 kJ . mol(-1), and Delta S double dagger = 17 +/- 19 J . (K . mol)(-1).
