Chiral Cu(ii), Co(ii) and Ni(ii) complexes based on 2,2′-bipyridine modified peptoids

Abstract

Helical peptoids bearing 2,2′-bipyridine, varied in their chiral bulky side chains and their N-terminus form complexes with Cu(II), Co(II) and Ni(II) via intramolecular binding. Chiral induction from the peptoid to each metal center could be only observed in some cases and is dependent on the identity of the N-terminus and on its position relative to the metal center.
