  摘要：

  Regioselective substitution of xanthone and its nucleophilic cleavage allow the synthesis of C-3 o-hydroxyaryl substituted 1,2-benzisoxazoles or their N-oxides by cyclodehydration or oxidative cyclization of their corresponding ketoxime precursors, respectively. Molecular modeling analysis and H-1 NMR spectra indicate an intramolecular H-bonding engaging phenol OH and the isoxazole ring N atom.

  Abstract 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
