  摘要：

  A novel template was synthesized for stabilizing beta-hairpin conformations in cyclic peptide mimetics. The template is a diketopiperazine derived formally from L-aspartic acid and (2S,3R,4R)-diaminoproline, the latter being available by an efficient synthetic route from vitamin C, The template was incorporated by solid-phase peptide synthesis into a cyclic loop mimetic containing the sequence (-Ala-Asn-Pro-Asn-Ala-Ala-template-). This mimetic was shown by NMR to adopt a stable beta-hairpin conformation in (D-8)DMSO solution. The template may prove to be: generally useful for creating small-molecule mimetics: of hairpin loops on proteins of diverse function.
