## Abstract Several N‐protected peptide amides, containing two aromatic residues spaced by one glycyl residue, have been enzymatically synthesized starting from P‐Ar‐OH and H‐Gly‐Ar‐NH~2~ (P is the protecting group and Ar is the aromatic residue) and using α‐chymotrypsin as the catalyst for the cou
