Xanthones in heterocyclic synthesis. An efficient route for the synthesis of C-3 o-Hydroxyaryl substituted 1, 2-benzisoxazoles and their N-oxides, potential scaffolds for angiotensin(II) antagonist hybrid peptides

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

Xanthones in heterocyclic synthesis. An efficient and general route for the synthesis of regioselectively substituted phthalazines

Xanthone undergoes regioselective substitution and nucleophically - triggered ring opening to the corresponding ketone. Hydrazone of the latter oxidatively rearranges to ortho-diacylarenes, which, then, with hydrazine gives regioselectively substituted phthalazines. Molecular modeling analysis and 1HNMR spectra indicate an intramolecular H-bonding engaging phenol OH and phthalazine N-3 atom.
