ISOQUINOLINE PROMOTED SYNTHESIS OF ARYL VINYL ETHERS FROM HETEROCYCLIC PHENOLS

7-Hydroxycoumarine undergoes a smooth reaction with dialkyl acetylene dicarboxylates inthe presence of isoquinoline to produce the corresponding alkyl dimethyl 2-((2-oxo-2H-chromen-7-yl)oxy)fumarate in good yields. When the reaction was performed by 6-hydroxyquinoline similar arylvinyl ethers were obtained.
