An enantioselective fluorination of 3‐functionalized oxindoles using electron‐rich amino urea catalyst is described. Various 3‐functionalized 3‐fluoro‐2‐oxindoles were obtained in good yields and enantio‐selectivity. The resulting enantioenriched 3‐methylene nitrile 3‐fluoro‐2‐oxindole product was found to inhibit indoleamine 2,3‐dioxygenase considerably.
Eighteen hexahydropyrrolo[2,3-b]indole derivatives were synthesized and evaluated their in vitro antifungal activities against five phytopathogenic fungal strains through the mycelium growth rate method. Analysis of the structure-activity relationship on these synthesized compounds revealed that the introduction of benzyl or substituted benzyl group at the C-3a or N-8 position of the pyrroloindoline
