Herein, the enzymaticcondensation of sidechain-protectedpeptidefragmentsusingsubtilisin A in anhydrousorganicsolvents is described. A screening with dipeptide Cbz-Val-Xxx carboxamidomethyl esters with H-Xxx-Val-NH2 nucleophiles was performed, wherein Xxx stands for every (sidechain-protected) amino acid residue. Finally, it was demonstrated that it is feasible to enzymatically condense larger
