Substitution of the fluoro or methoxy group in unprotected 2-fluoro- and 2-methoxybenzoic acids to afford N-aryl and N-alkyl anthranilic acids occurs upon reaction with lithioamides under mild conditions in the absence of a metal catalyst.
在温和条件下,无需金属催化剂,用锂酰胺与未保护的 2-氟和 2-甲氧基苯甲酸反应,可在芳基和烷基上取代氟和甲氧基,得到 N-芳基和 N-烷基邻氨基苯甲酸。
