Title: Conformational Preferences Of Ac-gly-nhme In Solution
Author: Cormanich

Abstract: The conformational behaviour of Ac-Gly-NHMe in nonpolar, polar and polar protic solutions was systematically studied in this work by theoretical calculations and experimental infrared and H-1 NMR spectroscopies. Ac-Gly-NHMe prefers a gauche conformer with a strong seven-membered intramolecular hydrogen bond for the isolated compound and in nonpolar solvents, but such preference changes in polar and polar protic solvents. Elucidation of Ac-Gly-NHMe preferences was also supported by studying the conformers of its CF3-C(O)-Gly-NHMe and Ac-Gly-N(Me)(2) derivatives in solution.
