In this thesis, I report the optimization of a metal-catalyzed cascade reaction for the synthesis of indolo[2,3-c]quinolinone (1) using 2-(2-bromophenyl)-N-(2-cyanophenyl)acetamide (19) as the starting material. First, I studied the effect of bases including NaH, NaOH, t-BuONa, and t-BuOK on this reaction by use of CuI as the catalyst and DMF as the solvent. The results showed that NaH and t-BuONa were the most reactive bases with CuI for the reaction. Consequently, NaH and t-BuONa were combined with different copper catalysts in DMF to further optimize the reaction. The results revealed that CuI, CuBr, Cu2O, CuBr·SMe2 showed good reactivity at 110 C. By lowering the reaction temperature, I found that CuBr and t-BuONa were the best combination for the reaction. Addition of a ligand or changing the reaction solvent redcued the yield. As a result, the optimal reaction conditions for the reaction are using t-BuONa as a base, CuBr as a catalyst, and DMF as a solvent. When the reaction was carried out at 110 C for 16 h, product 1 was obtained in 96% yield. I then applied the metal-catalyzed cascade reaction to synthesize alkaloid isocryptolepine (2). By addition of a monomethylation step into the cascade, 2 can obtained in three steps with a total yield of 72% from commercially available starting materials.
