  乳酸菌对（杂）芳基-脂肪族α-羟基羧酸的生物催化外消旋化。通过氧化-还原序列进行

  摘要：

  一系列（杂）芳基-和（二）芳基-脂肪族α-羟基羧酸的生物催化外消旋化已通过使用乳杆菌属的整个静息细胞实现。基本上温和的（生理）反应条件确保抑制不需要的副反应，例如消除、分解或缩合。使用副干酪乳杆菌 DSM 20207 无细胞提取物的辅因子/抑制剂研究表明，添加氧化还原辅因子 (NAD+/NADH) 导致外消旋化率明显增加，而在存在硫代-NAD+ 的情况下观察到强烈的抑制作用，这表明外消旋化是通过氧化还原序列进行的，而不是“外消旋酶”的参与。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

  Oxyfunctionalization of abundant carboxylic acids represents a direct approach to synthesizing α-hydroxy acids, which are valuable intermediates of various active pharmaceutical ingredients. Although ideal, the transformation is yet to be accomplished. Herein, enantiocomplementary C(sp3)–H oxyfunctionalization for the synthesis of α-hydroxy acids was realized by a cooperative strategy of substrate

  The Ru-catalyzed asymmetric hydrogenation of 2-oxo-4-arybutanoic acids to afford 2-hydroxy-4-arybutanoic acids was accomplished by employing SunPhos as chiral ligand and 1 M aq HBr as additive. The high enantioselectivities (88.4%-92.6% ee) and efficiency (TON=10,000, TOF=300 h(-1)) make this method efficient for the synthesis of an important intermediate, (R)-2-hydroxy-4-phenylbutanoic acid, for ACE inhibitors.

  日期：2010.9.3

  A challenging direct asymmetric hydrogenation of (E)-2-oxo-4-arylbut-3-enoic acids to give 2-hydroxy-4-arylbutanoic acids (85.4-91.8% ee) was achieved with a Ru catalyst based on SunPhos as the chiral ligand. Further investigation of the reaction revealed that partial isomerization of 2-hydroxy-4-arylbutenoic acids was involved in the hydrogenation process. Employing the reaction conditions to the hydrogenation of 2-oxo-4-phenylbutanoic acid resulted in better enantioselectivity (91.8% ee) and efficiency (TON = 2000, TOF = 200 h(-1)), which offers a useful method for the synthesis of a common intermediate for ACE inhibitors.
