Abstract:
    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.
