Abstract:
PURPOSE: A manufacturing method of a chiral alcohol compound is provided to regenerate the cofactor of an oxidoreductase with the high efficiency of 40% and to manufacture a chiral alcohol compound in a (R)-shape, thereby being with the optical activity of 80% from a ketone compound through an enzymatic reaction. CONSTITUTION: A manufacturing method of a chiral alcohol compound using a photo-biosystem comprises a step of a putting phosphorous-buffering solution, a cofactor of an oxidoreductase, an oxidation and reduction medium, a graphene-porphyrin optical catalyst, a non-polar organic solvent, an alcohol dehydrogenase, and a ketone derivative into a reactor and mixing the material while light is applied into the reactor under an inert gas atmosphere to conduct the reduction reaction of the ketone derivatives, thereby obtaining the chiral alcohol compound. The oxidation reduction medium is at least one selected from methyl viologen, a ruthenium (II) composite, and a rhodium (III) composite.
