Multi-Step Synthesis of Biologically Active Novel N-Benzyl-3,5-Bis(Arylidene)-Piperidin-4-Ones and Some Derived Bicyclic and Tricyclic Ring Systems as Macromolecules
This study reports the synthesis of some new bicyclic and tricyclic heterocyclic macromolecules incorporated pyrano[3,2-c]pyridine, 1,6-naphthyridine, and pyrimidonaphthyridine rings starting from new dienones, N-benzyl-3,5-bis(arylidene)-piperidin-4-ones. The chemistry involved the cyclocondensation of dienones with malononitrile in the presence of piperidine yielded the target 2-aminopyranopyridine-3-carbonitriles. The reaction of dienones with malononitrile or ethyl cyanoacetate in the presence of excess ammonium acetate afforded the corresponding 2-aminonaphthyridines and/or 2-oxonaphthyridine derivatives, respectively, in good yields. The 2,4-disubstituted pyrimido[4,5-b][1,6]naphthyridines were successfully achieved from the reaction of the 2-aminonaphthyridine derivatives with the appropriate reagents. The structures of the isolated products were determined by elemental analysis and spectral methods (FT-IR, H-1-NMR, and C-13-NMR). The cytotoxicity of some of the prepared derivatives was also investigated. [GRAPHICS] .
