Reaction of arylmethylidene derivatives of malononitrile dimer with 1,3-cyclohexanediones in anhydrous methanol in the presence of sodium methylate as catalyst affords 4-amino-5-aryl-2-methoxy-6-oxo-5,6,7,8,9,10-hexahydrobenzo[b][1,8]naphthyridine-3-carbonitrile. In the presence of strong electron-donor substituents in the benzene ring the reaction takes another route resulting in 4-amino-2-aryl-6-methoxypyridine-3

Abstract A novel series of 5,7-diamino-4-aryl-6-cyano-2-cyanoimino-3,4-dihydro-1H-pyrido[2,3-d]pyrimidines (aryl-CIDHPPMs) 3a–i was prepared via the one-pot four-component reaction of cyanoguanidine with aromatic aldehydes and malononitrile with molar ratio (1:1:2) using sodium methoxide as catalyst. These new polyfunctionlized aryl-CIDHPPMs were also synthesized by a classical route via reaction of

The synthesis of pyridine derivatives containing a buta-1,3-diene-1,1,3-tricarbonitrile fragment via the base-promoted reaction of benzalacetones and malononitrile dimer with subsequent oxidation is described. The influence of the substituents on the spectral-luminescent and electrochemical properties was also investigated.
