Solid-phase peptide synthesis started with N-Boc-L-leucine linked to a PAM resin (VII). Deprotection of the Boc group was effected by treatment with trifluoroacetic acid in CH2Cl2 to give leucine-resin (VIII). Sequential couplings with the respective protected amino acids were mediated by DCC and HOBt, and trifluoroacetic acid in CH2Cl2 was used for deprotection of the Boc groups. The following protected amino acids were sequentially coupled: N-Boc-L-proline (IX), N-Boc-L-isoleucine (XI), N-Boc-L-proline (IX), N-Boc-L-glutamic acid omega-benzyl ester (XIV), N-Boc-L-phenylalanine (XVI) and N-Boc-L-aspartic acid omega-cyclohexyl ester (XVIII) to afford the peptide resins (X), (XII), (XIII), (XV), (XVII) and (XIX), respectively.
