A synthetic sequence to the benzonaphthyridinone framework is described. The key step is a one-pot, base-catalyzed vicarious nucleophilic substitution followed by ring closure. Additionally, the synthesis represents the application of a vicarious nucleophilic substitution in the total synthesis of a cytotoxic aaptamine derivative.
