This dissertation describes the total synthesis of two natural products cladoniamide G and cladoniamide F which belong to the group of indenotryptolines that is closely related to the natural product class of indolocarbazoles. Key steps of the synthesis were the addition of an indole to a mesoxalic ester amide, a Suzuki cross-coupling of two indoles and an intramolecular lactam formation. Additionally, a method for the enantioselective addtion of indoles to mesoxalic ester amides was developed.
