Enzymatic kinetic resolution of methyl 2-methyl-4-oxopentanoate

Abstract:

The stereoselectivity of enzyme catalyzed reactions can be tuned by changing reaction conditions such as pH, temperature and with addition of co-solvents. Other alternatives for the modulation of the affinity and specificity between enzyme and extraneous organic compounds have been developed. In special, addition of salts can promote changes in enzyme solvatation which leads to changes in its interaction with the substrate. However, this approach is scarcely considered in biocatalytic reactions for preparative purposes. Herein, we describe the enzymatic kinetic resolution of methyl (RS)-2-methyl-4-oxopentanoate by a series of changes in the medium with merit to salt effect.
