resumo
Chemically, xanthones are oxygenated heterocyclic compounds with a dibenzo-け-pirone nucleus [1].
Natural derivatives have several types of substituents in different positions of their nucleus, which can be
associated to the pharmacological properties presented by this class of compounds [2].
Xanthones bearing aryl substituents are scarce and no natural derivatives have been reported with the
2,3-diaryl substitution pattern. Recently, we have reported the synthesis of several 2,3-diarylxanthones,
starting from 3-bromo-2-methylchromone.
