A high yielding environmentally benign protocol has been developed for the synthesis of 3-(pyrrol-1-yl)-indolin-2-ones using a Lewis acid surfactant combined catalyst in water.
Various 3-pyrrolylindolin-2-ones and pyrrolylindeno[1,2-b]quinoxaline were synthesized for the first time in high yields in water under neutral conditions by supramolecular catalysis involving β-cyclodextrin. The β-cyclodextrin can be recovered and reused a number of times without any loss of activity.
在中性条件下,通过β-环糊精的超分子催化,高产率首次合成了各种3-吡咯基吲哚-2-酮和吡咯烷基[1,2- b ]喹喔啉。β-环糊精可被回收并重复使用多次而不会损失任何活性。

efficiently with 4-hydroxyproline in the presence of 10 mol% of PMA/SiO2 in acetonitrile/water (4:1) under reflux conditions to furnish N-substituted pyrroles in excellent yields. Similarly, 11H-indeno[1,2-b]quinoxalin-11-ones also participated in this reaction.
