During solid-phase peptide synthesis (SPPS) the three nitrogen atoms of the guanidine group of Arg (Figure 9.1), being strongly nucleophilic, are prone to alkylation and subsequent Orn (ornithine) formation upon base-mediated decomposition [1], and therefore need to be protected. However, in common
Amino acid derivatives protected at the a-or side chain amino function with mono-as well as dimethoxytrityl were successfully prepared by a one-step procedure. These derivatives were evaluated for their utilization in solid phase peptide synthesis (SPPS), particularly with respect to the selective d
