Preparation

Acetonedicarboxylic acid can also be prepared by decarboxylation of citric acid in fuming sulfuric acid:^[2]

Applications

Acetonedicarboxylic acid and its esters such as dimethylacetonedicarboxylate are primarily used as building blocks in the synthesis of heterocyclic rings^[3] and in the Weiss–Cook reaction.^[4]

Acetonedicarboxylic acid is well known to be used in the Robinson tropinone synthesis.

The presence of β-ketoglutaric acid in human urine is diagnostic for the harmful gut flora such as Candida albicans.^[5]
