Abstract

The versatility of the pipecolic linker (Pip-linker) is illustrated by the synthesis of modified amino acids, C-terminal-modified pseudopeptides, and cyclic peptides, through side-chain anchoring of a lysine residue (see figure). Introduction of the first residue was easily accomplished and the Pip-linker revealed to be robust enough to support various chemical modifications.
