Abstract An intramolecular Diels− Alder strategy using 2 (1H)-pyrazinones was applied to generate a substituted perhydro-1, 7-naphthyridine ring system that served as a scaffold to construct the type VI β-turn mimic 2, featuring a cis-amide linkage between the central i+ 1 and i+ 2 residues. The synthesis permits mimicking of the amino acid side chains of the central dipeptide, a unique feature for external-turn mimics. Modeling studies indicated ...
