杂环合成中的氧杂蒽酮。一种合成 C-3 邻羟基芳基取代的 1,2-苯并异恶唑及其 N-氧化物、血管紧张素 (II) 拮抗剂杂合肽的潜在支架的有效途径
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.
