Induced axial chirality in biocatalytic asymmetric ketone reduction

Catalytic asymmetric reduction of prochiral ketones of type 4-alkylidene cyclohexanone with formation of the corresponding axially chiral R-configurated alcohols (up to 99% ee) was achieved using alcohol dehydrogenases, whereas chiral transition-metal catalysts fail. Reversal of enantioselectivity proved to be possible by directed evolution based on saturation mutagenesis (up to 98% ee (S)). Utilization of ketone with a vinyl bromide moiety allows respective R- and S-alcohols to be exploited as key compounds in Pd-catalyzed cascade reactions.
