Abstract
The reaction of benzylidenebarbituric acid and 1,3-dimethylbenzylidenebarbituric acid with malononitrile as well as with dimedone in piperidine is investigated. In reaction with malononitrile, substituted pyridine-3,5-dicarbonitriles are obtained, while with dimedone, xanthenes and/or 6-hydroxy-5-((2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-enyl)(aryl)methyl)-1,3-dimethyl pyrimidine-2,4(1H,3H)-dione derivatives are isolated.
