Novel ring fused heterocycles, 3, 10a-(11-azaetheno)-3,4,4a,10a-tetrahydro-[1]benzopyrano[2,3-b]pyridines were synthesized by the reaction of 2-chloropyrimidines with 2-allylphenols in the presence of a base. These compounds were formed by the intramolecular cycloaddition of initially formed 2-(2-allylphenoxy)pyrimidines.
