Summary o-Acetylation of cyclo-his-ser and cyclo-histhr in acetic acid/acetanhydride proceeds via intermolecular, and in the case of 4-hydroxyethyl-imidazole via intramolecular, acyl transfer. The highest rate of acetylation is observed with 4-hydroxyethyl-imidazole, and the most effective catalyst in the case of intermolecular acyl transfer is imidazole; derivatives of imidazole are less effective. Derivatives and peptides of serine are generally more reactive than those of threonine.
