Liu, Gaoxiaozheng published the artcileConcise synthesis of xanthones by the tandem etherification-Acylation of diaryliodonium salts with salicylates, Computed Properties of 596-38-3, the publication is Chinese Chemical Letters (2018), 29(6), 985-988, database is CAplus.
An efficient synthetic method for multi-substituted xanthones, e.g., I was developed. The reaction of diaryliodonium salts (RC6H4)2I+OTf– (R = H, 3-Me, 4-F, etc.) and salicylates R1C(O)2CH3 (R1 = 4-Br-2-HOC6H3, 3-hydroxythiophen-2-yl, 3-hydroxynaphth-2-yl, etc.) was employed for the preparation of the xanthones. This method proceeded through an intermol. etherification-acylation to give target heterocycles in good yields (up to 91%). Multi-substituted xanthones I were gained by shifting the substituent of salicylates or diaryliodonium salts.
