Removal of the Boc protecting group of (V) with trifluoroacetic acid was followed by coupling with N-Boc-D-leucine (VI) in the presence of HATU to provide (VII). The deprotection-coupling procedure was repeated using N-Boc-L-aspartic acid gamma-benzyl ester (VIII), N-Boc-L-valine (X), and N-Boc-D-Leucine yielding the depsipeptide resins (IX), (XI) and (XII), respectively.
