Abstract We describe novel scaffold designs for nonpeptidic α-helix mimetics. The tricyclic scaffolds contain triazoles and reproduce amino acid side chains i, i+ 3, and i+ 7. The three different scaffolds are synthetically readily accessible, allow the introduction of further substituents to increase the versatility, and are suitable for library design. A modular synthesis route using Cu I-and Ru II-catalyzed azide–alkyne [3+ 2] cycloadditions as ...
