  Enantioselective acylation of primary and secondary alcohols catalyzed by lipase QL from Alcaligenes sp.: A predictive active site model for lipase QL to identify which enantiomer of an alcohol reacts faster in this acylation

  摘要：

  Lipase QL (from Alcaligenes sp.)-catalyzed acylation of alcohols using isopropenyl acetate as the acylating agent in diisopropyl ether converted preferentially primary alcohols with an S configuration and secondary alcohols with an R configuration into the corresponding homochiral acetates. On the basis of observed enantiomer selectivities, a predictive active site model for lipase QL is proposed for identifying which enantiomer of a primary or a secondary alcohol reacts faster in this acylation.

  Because of the ubiquity of the secondary carbinol subunit, the development of new methods for its enantioselective synthesis remains an important ongoing challenge. In this report, we describe the first nonenzymatic method for the dynamic kinetic resolution (DKR) of secondary alcohols (specifically, aryl alkyl carbinols) through enantioselective acylation, and we substantially expand the scope of this

  由于二级甲醇亚基的普遍存在，开发其对映选择性合成的新方法仍然是一个重要的持续挑战。在本报告中，我们描述了通过对映选择性酰化对仲醇（特别是芳烷基甲醇）进行动态动力学拆分 (DKR) 的第一种非酶促方法，并且我们大大扩展了这种方法的范围，与酶促反应相比。简单地将醇的动力学拆分的有效方法与醇的外消旋化的活性催化剂相结合不会导致 DKR，因为钌基外消旋化催化剂与其中使用的酰化剂 (Ac(2)O) 不相容。动力学分辨率。机理研究表明，钌催化剂通过形成稳定的乙酸钌络合物而失活；this deleterious pathway was circumvented through the appropriate choice of acylating agent (an acyl carbonate). 这种新工艺的机理研究表明亲核催化剂的可逆 N-酰化，从催化剂到醇的酰基转移作为速率决定步骤，并且碳酸根阴

  unexplored 2,3-dihydroimidazo[1,2-a]pyridine (DHIP) has been shown to be a competent acyl transfer catalyst. Its chiral 2-phenyl derivatives obtainable in two steps from commercially available starting materials have proved to be effective acylation catalysts, giving high levels of enantioselectivity (s = 20-85) in kinetic resolution of secondary benzylic alcohols.

• Expanding substrate scope of lipase-catalyzed transesterification by the utilization of liquid carbon dioxide

  Secondary alcohols having bulky substituents on both sides of the chiral center are often poor substrates for most lipases. Here we reported that substrate scopes of two of the most used lipases, Candida antarctica lipase B and Burkholderia cepacia lipase, were found to be expanded toward more bulky secondary alcohols such as 1-phenyl-1-dodecanol and 2-methyl-1-phenyl-1-propanol by simply using them in liquid carbon dioxide as a solvent. The effects of solvents, reaction pressure, and pre-treatment of the enzyme with liquid CO2 on this acceleration phenomenon were also studied. (C) 2015 Elsevier Ltd. All rights reserved.

  Lipase QL-catalyzed acylation of secondary alcohols using isopropenyl acetate as the acylating agent in diisopropyl ether gave preferentially the corresponding acetate with an R configuration. On the basis of the results, a predictive active site model for lipase QL is proposed for identifying which enantiomer of a secondary alcohol reacts faster in this reaction.
