Coupling of enantioselective biooxidation of DL-1,2-propanediol and bioreduction of pinacolone via regeneration cycle of coenzyme.


PMID 16489454

Abstract

Enantioselective biotransformation of DL-1,2-propanediol to D-2-hydroxypropanic acid was first reported by the authors. In the biooxidation process, there were some by-product formed and thus influenced the e.e. value and output of the acid. Restricting oxygen in the reaction system and offering additional proton receptor to the system displayed approving effect. The latter method constructed regeneration cycle system of coenzyme. In the article, the bioreduction of pinacolone was coupled to the enantioselective oxidation. Yield of the acid was increased by 36% and e.e. value of the product approached 99%.
