报道了一种在碱性条件下通过2-炔基硝基苯和吲哚制备吲哚啉-3-酮衍生物的有效合成方法. 在该反应中, 由PPh3引发Wittig过程, 继而在碱作用下对吲哚进行活化, 以98%的产率得到C(2)-吲哚取代的吲哚啉-3-酮. 该反应可在不含过渡金属的条件下进行, 并通过对邻炔基硝基苯进行修饰, 合成了多种官能团化的吲哚啉-3-酮衍生物.

An efficient method for the preparation of indolin-3-one derivatives from 2-alkynylnitrobenzenes and indoles under alkaline conditions is described. In this reaction, the Wittig process is initiated by PPh3, and then the indole is activated under the action of the base to offer the indolin-3-one substituted by C(2)-indole in up to 98% yield. A variety of functionalized indolin-3-one derivatives were synthesized by modification of 2-alkynylnitroarenes under transition-metal free conditions.

Key words: PPh3, Wittig reaction, 2-alkynylnitroarene, indolin-3-one
