A concise synthesis of alkyl‐2,3‐dihydro‐1H‐isoindolin‐1‐one derivatives from 2‐formyl benzoic acid, β‐keto acid, and ammonia or primary amine was developed via a quaternary ammonium salt‐promoted multi‐component sequence of decarboxylative alkylation/lactamization reaction in water, in which the target products were obtained in good to excellent yields.
通过季铵盐促进的多组分序列开发了由2-甲酰基苯甲酸,β-酮酸和氨或伯胺合成烷基-2-3,3-二氢-1H-异吲哚-1-酮的衍生物在水中进行脱羧烷基化/内酰胺化反应的方法,其中以良好至优异的收率获得目标产物。
