Verwenden
1,3-Dimethylbarbituric acid is used as a catalyst in the Knoevenagel condensation of a series of aromatic aldehydes. It is also used in the synthesis of 5-aryl-6-(alkyl- or aryl-amino)-1,3-dimethylfuro [2,3-d]pyrimidine derivatives and enantioselective synthesis of isochromene pyrimidinedione derivatives.

7 molecular boat having an internal nanocavity (catalyst)-assisted Knoevenagel condensation reaction with various aromatic aldehydes. It has been synthesized by reacting 1,3-dimethylurea, malonic acid and acetic anhydride in acetic acid. It is widely used for the synthesis of various synthetic intermediates and heterocyclic compounds.
l?uterung methode
Crystallise the acid from water and sublime it in a vacuum. Also purify it by dissolving 10g in 100mL of boiling CCl4/CHCl3 (8:2) (1g charcoal), filtering and cooling to 25o. Dry it in vacuo [Kohn et al. Anal Chem 58 3184 1986]. [Beilstein 24 III/IV 1875.]
