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.
