Full details of a concise totalsynthesis of RA-VII (1) and deoxybouvardin (2) are described based on the implementation of an effective intramolecular Ullmann reaction as the key macrocyclization reaction in the preparation of the elusive 14-membered cycloisodityrosine subunit (33) of the bicyclic hexapeptides. Subsequent coupling of 34 to tetrapeptide 17 and macrocyclization with C 2 -N 3 amide bond
