A systematicstudy was performed to establish general synthesis protocols for forming enantiomerically pure macrocyclicdipeptide lactams. Focusing on macrocycles of 8-, 9-, and 10-memberedrings, effective syntheses were achieved by a sequence featuring peptide coupling of allyl- and homoallyl-glycine building blocks followed by ring-closingmetathesis. The 8-membered lactam-possessing cis-amide and
