One-pot synthesis of annulated 1,8-naphthyridines

Abstract Annulated 1,8-naphthyridines were synthesized by one-pot reaction of aromatic aldehyde, malononitrile dimer and enehydrazinoketone.

One-pot synthesis of 4-alkyl-2-amino-4H-chromene derivatives

Abstract A one-pot synthesis of 4-alkyl-2-amino-4H-chromene derivatives by base-initiated reactions of aliphatic aldehydes, malononitrile, and resorcinol in water is described.

Three-Component synthesis and characterization of nicotinamide derivatives containing a buta-1,3-diene-1,1,3-tricarbonitrile fragment

Abstract The synthesis of nicotinamide derivatives containing a buta-1,3-diene-1,1,3-tricarbonitrile fragment through the base-promoted three-component reaction of an aromatic aldehyde, an acetoacetamide and malononitrile dimer in the presence of an oxidant is reported. The HOMO-LUMO energy levels were estimated by cyclic voltammetry and UV-Vis measurements. The influence of aryl and carbomoyl substituents on the optical and electrochemical properties was also investigated. Graphical Abstract
