1. 1. Chemoenzymatic Dynamic Kinetic Resolution of Functionalized Secondary Alcohols

   Författare :Richard Lihammar; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Dynamic kinetic resolution (DKR) is the combination of a kinetic resolution with an in situ racemization and is a powerful method for obtaining optically active compounds. In this thesis various secondary alcohols are transformed to their corresponding enantiomerically enriched acetates by employing immobilized lipases as resolution catalysts and transition metal complexes as racemization catalysts.
