Fmoc-chemistry for the solid phase peptide synthesis of vancomycin- and teicoplanin-type peptides is described. Epimerization of highly racemization-prone arlyglycine derivatives is suppressed through optimized Fmoc-deprotection and coupling conditions. Starting from easily accessible Fmoc-protected aminoacids, this strategy enables the enantioselective synthesis of peptides corresponding to intermediates
