Reaction of D-glucaro-1, 4-lactone (I) and -6, 3-lactone (II) with ammonia and alkyl-amines afforded a monoamide (XII and V), N-alkyl-D-glucaro-1-amide 6, 3-lactone (XIV) and N-alkyl-D-glucaro-6-amide 1-acid (IX). XIV and IX formed D-glucaric acid N, N-dialkylamide (X) by a disproportionation-like reaction but XII and V underwent hydrolysis into a monoammonium salt (VI) of D-glucaric acid by the same reaction.
