Exploring solid-phase approaches for the preparation of new β-lactams from amino acids
Two solid-phase approaches, involving the base-assisted intramolecularalkylation of N-chloroacetyl-Phe derivatives anchored to appropriatesolid supports, were investigated for the preparation of novel β-lactams. ...

Studies on the synthesis of β-keto esters derived from dipeptides: search for a low-epimerizing method
β-Keto esters derived from dipeptides areprepared by application of common methodologiesemployed for the synthesis of amino acid-derivedβ-keto esters; however, epimerization of theC-terminal residue occurred t...

Constrained C-terminal hexapeptide neurotensin analogues containing a 3-oxoindolizidine skeleton
In order to enforce different spatial orientations in the C-terminal hexapeptide of neurotensin (NT8−13) and to gain information about the importance of the 10–11 peptide bond for binding to NT receptors, the Pro
