EACTION of 2-acetyl-5,6,7,8-tetrahydronaphthalene (1) with different aromatic aldehydes yielded the corresponding cyanopyridone derivatives 2a,b.Upon heating of 2a with chloroacetone, led to the formation of furopyridine derivative 4, while the reaction of compounds 2a,b with ethyl bromoacetate afforded 3-cyanopyridinyl derivatives 5a, b.Condensation of 5a,b with different amines gave the compound...
