Four model compounds and four dipeptides containing N-aminoazetidinecarboxylic acid (AAzC) and a particular stereoisomer of 2-aminocyclobutanecarboxylic acid (ACBC) were studied to establish their solutionstate conformational preferences, particularly regarding the ability of AAzC to induce a three-center hydrogen-bonded folding feature known as a “hydrazino turn”. On the basis of IR and NMR experiments
