A ruthenium-catalyzed asymmetric transfer hydrogenation of racemic isoflavanones with dynamic kinetic resolution yields virtually enantiopure isoflavanols as single diastereomers. Subsequent oxidation gives rise to isoflavanones in high enantiomeric purities.
An object of the present invention is to provide enzymes associated with equol synthesis, genes coding such enzymes, and a process for producing equol and its intermediates using the enzymes and genes.
The present invention provides a dihydrodaidzein synthesizing enzyme, tetrahydrodaidzein synthesizing enzyme, equol synthesizing enzyme, and genes coding these enzymes. The present invention also provides a process for synthesizing dihydrodaidzein, tetrahydrodaidzein, and/or equol using these enzymes.

Methods for the hydrogenation of isoflavones are described which provide access to workable quantities of isoflavan-4-ols, isoflav-3-enes, and isoflavans. The isoflavone derivatives can be obtained in high purity and in near quantitative yields whilst employing pharmaceutically acceptable reagents and solvents.
