  摘要：

  基于1-四氢萘酮、1-茚酮和4-克罗莫酮骨架的立体化学纯化合物，含有全碳四元立体中心，已通过采用脂肪酶PS（来自布尔克霍尔德菌）催化的动力学分离合成。这些骨架进一步通过微生物酮还原酶（来自地霉菌、帕氏酵母和黑曲霉）进行了功能化，以获得立体化学纯的二醇，经过进一步的合成操作，得到新型环状化合物。

  Racemic compounds containing a quaternary stereocenter (having hydroxymethyl and alkyl group adjacent to keto functionality) based on chromanone, alpha-tetralone, and indalone scaffolds have been synthesized. An enzymatic irreversible transesterification approach has been applied to generate the pure enantiomers in a stereocontrolled fashion. The pure enantiomers of some alpha,alpha-dialkylated carbonyl compounds have been synthesized by this method. (C) 2008 Elsevier Ltd. All rights reserved.

  Stereochemically pure compounds containing an all carbon quaternary stereocenter based on 1-tetralone, 1-indanone and 4-chromanone scaffolds have been synthesized by employing Lipase PS (Burkholderia cepacia) catalyzed kinetic resolution. These scaffolds are further functionalized by microbial ketoreductase enzymes (Geotrichum candidum, Candida parapsilosis and Aspergillus niger) to access stereochemically pure diols which, on further synthetic manipulation, yield novel cyclic compounds.
