Interesting Synthetic Approaches Towards [1]Benzopyrano[4,3-b]quinolines via Intramolecular Reaction of Nitrilium Salts

Abstract

The o-allyloxybenzanilides 2a,b,d and o-propargyloxybenzanilides 3af are prepared and converted to the corresponding dihydro[1]benzopyrano[4,3-b]quinolinium hexachloroantimonate 6a and [1]benzopyrano[4,3-b]quinolines 9ae, 10 upon treatment with PCl5 followed by SbCl5.
