Abstract
By sonication in MeOHN-m-(phenylboronic acid)-2,2'-bipyridine-5-carboxylami
de easily formed its bidentate boronate sugar ligands. Solutions of the cor
responding Cu(I) and Fe(II) complexes showed opposite CD effects for the D
and the L form of the sugar. The stoichiometry of the metal complexes was d
etermined by Job plots and by mass spectrometry. A macrocyclic structure, t
hat includes ten cycles, is proposed as the most probable CD-active species
