Products of Anthraquinone Reduced by Zinc Powder in Ice Acetic Acid

The reduction products of hydroxyl anthraquinone by using zinc powder in acetic acid were(obtained).The C[ZJLX,Y]C bonds on the anthraquinone ring can be reduced by the zinc in the acetic acid and the carbonyls of anthraquinone are not reduced.After the hydroxyls of anthraquinone have been protected,the carbonyls of(anthraquinone) are reduced and the C[ZJLX,Y]C bonds on the anthraquinone ring not reduced.Four new reduction products of anthraquinone were prepared with this method.The structures of these products were confirmed by NMR,IR and MS.
