A facile synthesis of xanthenes and acridines based on a cascade nucleophilic addition−cyclic Michael addition process of arynes and phenols/anilines substituted with α,β-unsaturated groups at the ortho positions is described. The reaction has also been successfully extended to the synthesis of 9-spiro-xanthene and acridine derivatives with potential biochemical interest.
