Cu-catalyzed reaction of phenols with electron-rich arene or heteroarene ligands of unsymmetrical diaryl-λ3-iodanes is a key step in the developed one-pot two-step method for intermolecular para-selective C–H aryloxylation of heteroarenes and arenes.
An LDA-induced regiospecific and general conversion of diaryl ether 2-carboxamides 4 into substituted xanthones 5, including natural products, 2-hydroxy-1-methoxyxanthone (8) and 6-deoxy-jacareubin (14), is described.
