intramolecular amidation, has been established for efficient synthesis of 2H-1,4-benzoxazin-3-(4H)-ones from o-halophenols and 2-chloroacetamides. A varity of substrates afford the desired products in good to excellent yields. It is particularly attractive for synthesis of a library of 2H-1,4-benzoxazin-3-(4H)-ones.
已经建立了由分子间 O-烷基化和自发分子内酰胺化组成的 Pd 催化级联协议,用于从邻卤苯酚和 2-氯乙酰胺有效合成 2H-1,4-苯并恶嗪-3-(4H)-酮。各种底物以良好到极好的产率提供所需的产品。它对于合成 2H-1,4-benzoxazin-3-(4H)-ones 库特别有吸引力。
