CH,O CHO OH H- HO H HO H HCN H OH OH H- OH H- -OH H- CH2OH CH2OH The Wohl degradation is a series of reactions that shorten an aldose chain by one carbon, it is almost the exact opposite of the Kiliani In this reaction the aldose aldehyde carbonyl group is converted into a nitrile. The resulting cyanohydrin loses HCN under basic cone Conversion of the aldehyde to a nitrile is accomplished...
