Nitriles in heterocyclic synthesis: Synthesis of pyridine, pyrone, benzocoumarin and pyridocoumarin derivatives
Polysubstituted pyridines (IIa) and pyrones (IIIc) have been synthesized from cinnamonitriles (Ia,c) and 2-hydroxyacetophenone.The coumarin derivatives (V) are obtained by the reaction of 3-cyano-4-methylcoumarin (IV) with nitrostyrene (If).The reaction o
