Easy Access to Pyranoacridines, Pyranoxanthenes, and Arylchromenes Through a Domino Reaction

Abstract A series of pyrano[2,3,4‐ kl ]acridines has been synthesized through an unprecedented domino reaction involving1‐hydroxy‐3‐methoxy‐10‐methylacridone and Grignard reagents. This method has been successfully applied to xanthone, anthracenone, and benzophenone derivatives, thus providing novel access to pyranoxanthenes, dihydronaphthochromenes, and arylchromenes.
