with wide-ranging biological activities and medicinal values, and therefore, efficient approaches to their synthesis remain in demand. Herein, a novel and operationally simple method to generate indolin-3-ones is reported by using a tandem reaction of N-methylbenzylamines and methyl 2-fluorobenzoates mediated by the LiN(SiMe3)2 and CsF system (34 examples, 30–85% yields). The synthesis of C2-quaternary
Indolin-3-ones 是重要的杂环化合物,具有广泛的生物活性和药用价值,因此仍然需要有效的合成方法。本文报道了一种新颖且操作简单的方法,通过使用由 LiN(SiMe 3 ) 2和 CsF 系统介导的N-甲基苄胺和 2-氟苯甲酸甲酯的串联反应来生成 indolin-3-ones(34 个实例,30-85 % 产量)。 C2-季吲哚啉-3-酮的合成进一步证明了这些串联反应的潜在实用性。
