Synthesis of aminopyridines from azidopyridines and tetrazolo[1,5-a]pyridines

3-Cyano-1,2-dihydro-pyridine-2-ones 2 have been synthesized via the base-catalyzed cycloaddition of arylidenecyanoacetamide 1 with acetophenone. Chlorination of 2 with POCl3/PCl5 mixture gave the corresponding chloropyridines 3. Reac

CYCLIZATION OF NITRILES. IX. SYNTHESES BASED ON 2-ARYL-3-AROYL-1,1-DICYANOPROPANES

2-Aryl-3-aroyl-1,1-dicyanopropanes and 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes were synthesized from chalcones and malononitrile and were converted into 4,6-diaryl-2-bromo-3-cyanopyridines and 3-cyano-2(1H)-pyridinethiones.The 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes proved convenient intermediates for the production of the corresponding cyclopropanes and other compounds.By their reaction with urea a new method was developed for the production of substituted 3-cyano-2(1H)-pyridinethiones.The 2-bromo-3-cyanopyridines contain a mobile bromine atom readily exchanged for the various nucleophilic residues of alcohols and amines and for iodide, and cyano and thiocyanato groups.The 3-cyano-2(1H)-pyridinethiones were used in the synthesis of 3-aminothienopyridines through the isolated 2-Z-methylthio-3-cyanopyridines.
