Conformational properties of O-alkylated benzamides

In this article, we report the synthesis, solid-state and solution-state conformational studies of O-alkylated aromatic benzamides based on two scaffolds. Intramolecular hydrogen bonding provides conformational pre-organization and side chains can interact with each other within a molecule. In the solid-state three-dimensional arrangement, the molecules further interact with each other through non-covalent interactions. Given, the demonstrated potential of this class of scaffolds to act as helix mimetics for the inhibition of protein-protein interactions (PPIs), these results provide key insight for future inhibitor design.
