Elix, Musidlak, Sala and Sargent 128) have reported a novel synthetic route to xanthones which used an Ullmann reaction to produce a diaryl ether and its subsequent condensation to yield the xanthones (route C). This route is exemplified by the synthesis of thiophaninic acid (136) (Scheme 16). [Pg.131]
