The reaction of diaryliodonium salts and salicylates was employed for the preparation of the xanthones. This method proceeded through an intermolecular etherification-acylation to give target heterocycles in good yields（up to 91%）. Multi-substituted xanthones were gained by shifting the substituent of salicylates or diaryliodonium salts展开更多
