We here describe the use of three-component reactions to synthesize tricyclic pyridine ring-fused 2-pyridones. The developed protocols have a wide substrate scope and allow for the installation of diverse chemical functionalities on the tricyclic central fragment. Several of these pyridine-fused rigid polyheterocycles are shown to bind to Aβ and α-synuclein fibrils, which are associated with neurodegenerative diseases.
