Kinetic resolution via oxidation of endo-bicyclic octen- and heptenols with Bacillus stearothermophilus
摘要:
Kinetic resolution of die racemic endo-bicyclic octenol and heptenols via oxidation with Bacillus stearothermophilus is described. The enantiomerically pure ketones and alcohols can be obtained varying the oxidation time.

Stereocontrolled Access to Isoprostanes via a Bicyclo[3.3.0]octene Framework
stereocontrolled strategy toward the total synthesis of isoprostanes based on a bicyclic alpha,beta-epoxy ketone intermediate 6. Bicyclo[3.3.0]octene scaffold permitted stereodirection of reagents allowing stereoselective epoxidation, diastereoselective ketone reduction, and regioselective epoxide opening otherwise not accessible with a simple cyclopentene framework.

The first example of oxidation with bacteria in heptane is reported. The kinetic resolution of endo-bicyclic octen- and heptenols is obtained. The methodology is simpler and the volume of the reactions is smaller than in water.
