amongst the series with IC50 value 0.02 µM and 0.8 µM against HT-29 and Hepg2 cell lines, respectively, and compound 3i was most active amongst the series with IC50 value 1.5 µM against A549 cells. Molecular docking study and mechanism of reaction have briefly beendiscussed. This method is better than previous reports in view of yield and substrate scope including electron deficient indoles.

An efficient, two step synthesis of 3-(pyrrolidin-3-yl)indoles 4 is described. Indoles react with maleimides in refluxing acetic acid affording 3-(indol-3-yl)succinimides 6. Reaction times and yields depend on the substituents on the indole 5. Direct reduction of the succinimides 6 with LAH affords the desired conformationally restricted tryptamine derivatives 4.
