for reducing an .alpha.,.beta.-unsaturated ketone of the present invention includes the step of treating the .alpha.,.beta.-unsaturated ketone with a silyl compound in the presence of a Lewis acid and alcohol to selectively reduce the carbonyl group of the .alpha.,.beta.-unsaturated ketone....
The hydrogen transfer mechanism of cofactor reduction and recycling processes in the yeast reduction of α,β-unsaturated ketone was studied by using quantitative isotope tracing close to natural abundance measured by 2H NMR. In the reaction, the active cofactor is NADPH. The cofactor-transferred hydr...
