Imidazolines as Amide Bond Replacements

This work describes the use of a 2,5,5-trisubstituted imidazoline as an amide bond replacement.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 an

Synthesis of A Homochiral α,α-Disubstituted α,β-Diamino-acid

The synthesis of a homochiral α,α-diamino-acid is described from norleucine using stereospecific alkylation of a homochiral oxazolidinone enolate; an optically active pseudotetrapeptide analogue of CCK-4 is prepared to show an application of such diamino-
