Control of helicity in C3-symmetric systems by peptide-like β-turns
摘要:
Cyclic imidazole-containing hexapeptides with three arms bound to the peptide scaffold via the secondary nitrogen atoms of the imidazoles are presented; these arms, together with a part of the macrocycle, form peptide-like beta-turns making their helicity predeterminable and allowing the diastereoselective synthesis of A-metal complexes.
