Stabilisation of β-hairpin conformations in a protein surface mimetic using a bicyclic template derived from (2S,3A,4R)-diaminoproline

A trifunctional template, derived by formal coupling of (S)-aspartic acid and (2S,3R,4R)-diaminoproline (available from vitamin C) as a diketopiperazine, was incorporated by solid-phase peptide synthesis into a protein loop mimetic containing the sequence
