开发了多取代呫吨酮的有效合成方法。二芳基碘鎓盐和水杨酸盐的反应用于制备呫吨酮。该方法通过分子间醚化-酰化反应以良好的产率（高达 91%）得到目标杂环。通过改变水杨酸盐或二芳基碘鎓盐的取代基得到多取代的呫吨酮
An efficient synthetic method for multi-substituted xanthones was developed. 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
