Abstract: | The 1H NMR study of fulleroproline derivative Ac-Fpr-OtBu and its Pro analogue Ac-l -Pro-OtBu over a range of temperatures in toluene-d8 solution has enabled the comparison of their equilibrium and activation parameters for the trans/cis interconversion around the amide partial double bond. © 1998 European Peptide Society and John Wiley & Sons, Ltd. |
