SYNTHESIS OF XANTHENES, INDANES, AND TETRAHYDRONAPHTHALENES VIA INTRAMOLECULAR PHENYL–CARBONYL COUPLING REACTIONS

Abstract

Benzaldehydes and acetophenones bearing tethered carbonyl chains underwent the intramolecular phenyl–carbonyl coupling reactions, by mediation of samarium diiodide and hexamethylphosphoramide, to afford the xanthenes and fused benzocarbocyclic compounds containing carbonyl and hydroxyl substituents.
