Fmoc-Sieber-polystyrene resin

Fmoc-Sieber amide resin is an acid-labile carrier for solid phase synthesis of peptide amides. Cleavage can be achieved with only 1% TFA in DCM making them an ideal carrier for the synthesis of protected peptide fragments in fragment condensation strategies for the synthesis of long peptides. It has also been used in organic synthesis of acid-sensitive compounds, for targeted synthesis of primary amines and N-alkylated secondary carboxyamides.
