Sieber Resin
9-Fmoc-Aminoxanthen-3-yloxy-polystyrene resin A hyper acid-labile linker or the Fmoc SPPS of protected amides via mild 1% TFA cleavage. The sieber amide resin can be readily reductively alkylated to provide a support suited to the synthesis of secondary carboxamides. This resin has also been employed to produce protected peptide fragments in wich the C-terminal carboxylic acid group is blocked as a hydroxymethylphenoxy-β-alaninamide ester.
