Abstract
The studied 1-(2-benzothiazolyl)-2-pyridones Va-Vf were prepared from N-(2-benzothiazolyl)cyanoacetamide (II) which on reaction with 4-substituted benzaldehydes afforded 3-aryl-N-(2-benzothiazolyl)-2-cyano-2-propenamides IVa-IVg. Compounds IVa-IVf were cyclized with malonodinitrile in the presence of piperidine to give the corresponding pyridones Va-Vf.
