  Enzymatic desymmetrization of 3-arylglutaric acid anhydrides

  摘要：

  Optically active (R)- and (S)-3-arylglutaric acid monoesters 3 were synthesized in quantitative yields and good stereoselectivities by lipase-catalyzed desymmetrization of the corresponding 3-arylglutaric anhydrides 2 with alcohols. It was observed that the stereochemical outcome of the reaction was influenced by the substituents present on the aromatic ring. The influence of the enzyme, alcohol, and solvent was systematically examined. Absolute configurations of the monoesters 3 were assigned by chemical correlation to corresponding lactones 4.

  固定化热地芽孢杆菌脂肪酶催化连续分批反应器操作中3-苯基戊二酸二甲酯的不对称水解

  摘要：

  这项工作的主要目的是研究固定化的热芽孢杆菌的立体选择性行为。顺序分批反应器中的脂肪酶（BTL2），以部分和不对称水解戊二酸三甲酯（DMFG）作为模型反应。为了实现此目标，将BTL2脂肪酶固定在琼脂糖凝胶上，并用溴化氰和辛基（单官能载体）以及十一醇-乙醛基和辛基-环氧化物基团（杂官能载体）固定二氧化硅载体，以确定固定过程中酶取向的影响它们的催化性能 在DMFG的水解中，用十一烷醇-乙醛酸Sepharose获得的生物催化剂被证明是最立体的，在水性介质中对映体过量（ee）值为90％。此行为可归因于脂肪酶在支持物上的方向差异。在顺序分批反应器操作中，ee在前两批中保持恒定；但是，从第三批开始，ee上的酶含量略有下降，这可能是由于在反应条件下酶的构象发生了变化。最后，高纯度在顺序间歇反应器操作中生产的戊二酸S-甲基-3-苯基酯显示，该生物催化剂可以重复使用至少两次，而不会失去立体选择性，有利于降低工艺成本。

  chloramphenicol‐base‐derived thiourea organocatalysts, (1S,2R)‐12 a–f and (1R,2R)‐15 a–c, and their use in the enantioselective alcoholysis of meso‐anhydrides are described. In particular, hemiesters afforded excellent enantioselectivities if low loadings of (1S,2R)‐12 a–f were used. Almost no enantioselectivities were achieved with the use of (1R,2R)‐15 a–c. This technique was used to synthesize (R)‐(−)‐baclofen
