  Enzymatic Resolution, Desymmetrization, and Dynamic Kinetic Asymmetric Transformation of 1,3-Cycloalkanediols

  摘要：

  An efficient desymmetrization of cis-1,3-cyclohexanediol to (1S, 3R)-3-(acetoxy)-1-cyclohexanol ((R, S)-2a) was performed via Candida antarctica lipase B (CALB)-catalyzed transesterification, in high yield (up to 93%) and excellent enantioselectivity (ee's up to > 99.5%). (R, R)-Diacetate ((R, R)-3a) was obtained in a DYKAT process at room temperature from (1S, 3R)-3-acetoxy-1-cyclohexanol ((R, S)-2a), in a high trans/cis ratio (91: 9) and in excellent enantioselectivity of > 99%. Metal- and enzyme-catalyzed dynamic transformation of cis/trans-1,3-cyclohexanediol using PS-C gave a high diastereoselectivity for cis-diacetate (cis/trans) 97: 3). The (1R, 3S)-3-acetoxy-1-cyclohexanol (ent-(R, S)-2a) was obtained from cis-diacetate by CALB-catalyzed hydrolysis in an excellent yield (97%) and selectivity (> 99% ee). By deuterium labeling it was shown that intramolecular acyl migration does not occur in the transformation of cis-monoacetate to the cis-diacetate.

  In this work we developed C₂-symmetric chiral nucleophilic catalysts which possess a pyrrolidinopyridine framework as a catalytic site. Some of these organocatalysts effectively promoted asymmetric desymmetrization of meso-diols via enantioselective acylation.

  在这项工作中，我们开发了具有吡咯啉吡啶骨架作为催化位点的C₂-对称手性亲核催化剂。其中一些有机催化剂有效地促进了通过对映选择性酰化实现对meso-二醇的不对称去对称化。
