STUDIES ON THE CHEMICAL TRANSFORMATIONS OF SIMPLE CONDENSATES DERIVED FROM 3-FORMYLCHROMONE UNDER NUCLEOPHILIC CONDITIONS

The chemical reactivity of the simple condensates 1 and 2, derived from 3-formylchromone, was studied towards some nucleophilic reactions. Reactions of compounds 1 and 2 with some nucleophilic reagents mainly proceed via nucleophilic addition at the exocyclic vinyl bond followed by either elimination or cyclization during the course of reactions. A variety of products were obtained depending on the substrate and the nucleophile used.
