  • Triazole tethers have been explored for stabilization of secondary structures in peptides. Despite the utility of this approach, cyclization efficiency in complex peptides remains a significant challenge. A robust, on-resin protocol for side chain to side chain macrocyclization by CuAAC is described. This protocol was applied to the synthesis of a series of 21 amino acid helical peptides presenting a binding dipeptide motif from the membrane proximal external region (MPER) of HIV-1 gp41.
