C-glycosyl beta(2)- and beta/beta(2)-peptides with three to eight amino acid residues have been prepared. Solution and solid-phase peptide syntheses were employed to assemble beta(2)-amino acids in which C-glycosylic substituents are attached to the C-2 position of beta-amino acids. Conformational analysis of the C-glycosyl beta(2)-peptides using NMR and CDspectra indicates that the tripeptide can form
