A versatile strategy to halogenated xanthones I (R1 = H, R2 = Br; R1 = Br, R2 = H; R3 = H, Cl) that relied on a modular coupling of vanillin derivatives with a dibromoquinone has been developed. Depending on the reaction conditions, either the 6- or the 7-bromo heterocycles can be obtained in a divergent manner. These heterocycles were readily further elaborated by sequential Sonogashira couplings, and the sequence might be successfully applied to substructures of the antibiotic lysolipin.
