The total synthesis of cladoniamide G, a cytotoxic compound against MCF-7 breast cancer cells (10 mu g/mL), was accomplished. Key steps in the sequence include oxidative dimerization of 3-acetoxy-5-chloroindole and a tandem process incorporating three steps: bimolecular carbonyl addition, lactam formation, and carbamate removal.
