Evaluation of Hydrogen Bonding Complementarity between a Secondary Sulfonamide and an α-Amino Acid Residue

Abstract

[structure: see text] We report an initial step toward the development of sulfonamide-based complements for extended peptide strands. A molecule containing one secondary sulfonamide unit and one valine residue linked by a turn-forming segment was found by IR and NMR to exhibit a doubly hydrogen-bonded folding pattern in chloroform.
