A novel carbon-carbon double-bond reductase was isolated from the cells of baker's yeast. The reduction of α,β-unsaturatedketones catalyzed by this enzyme affords the corresponding saturated (S)-ketones selectively.

Bakers’ yeastreduction of α,β-unsaturated ketones affords optically active saturated ketones contaminated by allylic and saturated alcohols as minor components. Stereoselectivity of the reduction of carbon–carbon double bond strongly depends on the structure of β-aryl substituent. The bakers’ yeastreduction of β-phenyl enones gives saturated ketones in moderate stereoselectivity. Stereoselectivity
