This work describes the use of a 2,5,5-trisubstituted imidazoline as an amidebondreplacement. The replacement is incorporated into dipeptide derivatives of Phe, Trp, Lys and Nle and also into the CCK-4 analogue Trp-Nle-Asp-Phe-NH2 and the pentagastrin analogue Gly-Trp-Nle-Asp-Phe-NH2. The amidebondreplacement is synthesised in enantiomerically and diastereomerically pure form.
