FT-IR spectroscopy and in the solidstate by using X-ray diffraction. The conformational behavior of these compounds has been compared to that of the analogous Ac3c and l- or d-Phe-containing dipeptides. When associated to proline, the cyclopropane residues in the so-called i + 2 position exhibit a marked tendency to β-folding in solution, even in DMSO. The type II β-turn is generally favored, but the

A new efficient synthesis of 1-aminocydopropanecarboxylic acid (ACC) from methyl 2-diphenylmethyleneaminoacrylate in nearly quantitative yield has been developed. The key step in the synthesis is the removal of both protecting groups in mild conditions and in quantitative yield to afford ACC.
