Carbohydrates with 1,4 glycosidic bonds like maltose, lactose, dextrin or starch react with primary amines as well as amino acids or proteins to give i.e. 3‐hydroxy‐2‐methyl‐4‐pyridones 5 and 3‐hydroxy‐2‐methyl‐4‐pyridonimines 7. A generally applicable synthesis of compounds of this type is described. The pyridones 5 and pyridonimines 7 are strongly complexing agents. Molybdenum‐derivatives, for instance, are suitable as fairly stable oxidation catalysts.
