Abstract: Abstract A series of xanthone derivatives were synthesized by rhodium-catalyzed cycloaddition and sequential oxidation. The derivatives synthesized for excellent yields, including electron-withdrawing and electron-donating substituents, demonstrated the wide applicability of the proposed approach. The xanthones… read more here.

Abstract: Abstract We report the rapid synthesis of various cycloheptane-fused chromones and an oxepine fused flavone in 5 steps from the corresponding 2-hydroxy acetophenone. Furthermore, we describe the synthesis of xanthones, in moderate to good yield,… read more here.
