USPTO Abstract
A method for reducing an α,β-unsaturated ketone of the present invention includes the step of treating the α,β-unsaturated ketone with a silyl compound in the presence of a Lewis acid and alcohol to selectively reduce the carbonyl group of the α,β-unsaturated ketone. According to this method, a deoxy-compound can be obtained from the α,β-unsaturated ketone by selectively reducing the carbonyl group without reducing an α,β-unsaturated bond.
