  Simple preparation of enantiomeric Michael adducts of thiophenol to chalcones: easily available new chiral building blocks

  摘要：

  A facile and enantioselective method for the multigram preparation of the title compounds is described. The Michael addition of thiophenols to chalcones catalyzed by (+)-cinchonine, followed by crystallization, led to the corresponding adducts 2 in up to > 95% e.e. The stereoselective Beckmann rearrangement of the oxime of (+)-1,3-diphenyl-3-phenylsulfanylpropan-1-one 2a gives the anilide of (R)-(+)-3-phenyl-3-phenylsulfanylpropanoic acid (as determined by X-ray analysis) and alcoholysis leads to the corresponding enantiomerically pure ethyl ester.

• Investigating the efficacy of green solvents and solvent-free conditions in hydrogen-bonding mediated organocatalyzed model reactions

  restricts its application to reactions that require non-polar solvents. Furthermore, pursuing solvent-free conditions, even without liquid substrates, might result in similar conversion rates with reduced catalyst loading. These findings highlight the potential of exploring solvent-free conditions when enantioselectivity is not of concern. Based on the results, solvent-free conditions and bio-based solvents

  在这项研究中，我们深入研究了使用绿色溶剂或无溶剂条件下进行的各种反应，利用氢键有机催化来推进化学合成中更可持续的实践。结果表明，环戊基甲基醚有可能取代己烷和甲苯等非极性有机溶剂，并具有相当的对映选择性和产率。液化或超临界CO 2的非极性性质限制了其在需要非极性溶剂的反应中的应用。此外，追求无溶剂条件，即使没有液体底物，也可能在减少催化剂负载的情况下产生相似的转化率。这些发现凸显了在不关心对映选择性时探索无溶剂条件的潜力。根据结果​​，无溶剂条件和生物基溶剂可以作为传统有机溶剂的可行替代品，而不会影响性能。预计这将影响化学家在该领域的方法开发中实现反应优化的方式，从而促进更广泛地采用环保方法。

  A biomimetic, inexpensive, and simple method for the stereoselective thio-Michael addition of thiols to chalcones has been developed using bovine serum albumin (BSA) as a catalyst. Optically active products are obtained in high yield and with enantiomeric excesses of up to 70%. (C) 2011 Elsevier Ltd. All rights reserved.
