A method 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. According to this method, a deoxy-compound can be obtained from the .alpha.,.beta.-unsaturated ketone by selectively reducing the carbonyl group without reducing an .alpha.,.beta.-unsaturated bond.
