    • Note also that the observed dihedral angles between the two naphthalene ring systems in each binaphthyl unit of 3a (74.59° and 88.03° for one conformer, and 69.90° and 82.20° for the other one) are only slightly higher than that observed in the structure of its acyclic precursor 1a (69.05°), which indicates that the steric strain within 3a is low:

    • Evolution of 3a into 2a with longer reaction times was not observed, thus allowing us to discard its participation as a reaction intermediate In all the reactions depicted in Scheme 2 formation of minor amounts of macrocyclic dimers related to 3a, as well as higher oligomers, was evidenced from the NMR spectra of the crude reaction mixtures. One of these dimers, i.e.3b, could be isolated in pure form (9%) allowing its unambiguous characterization (see ESI)
