ABSTRACT
While malononitrile and cyanoacetamide react with 2,3-dimethox-y benzylideneacetophenone to give pyridine and pyridone derivatives, through Michael condensation, the reaction with succinic ester condenses in the Stobbe type affording the half-ester [IIa]. This undergoes cyclization to five membered ring compounds via two different routes. The synthesis of isoxazole [IX], oxadiazole [XIa] and thiazole [Xlb] is also described. The biological activity of these compounds is evaluated and discussed
