Abstract

Asymmetric synthesis of enantioenriched zigzag-type molecular belts featuring copper/H8-binaphthol-catalyzed kinetic resolution of a resorcinarene derivative and subsequent transformations was developed. The acquired rigid and C4-symmetric belt exhibited remarkably enhanced photophysical and chiroptical properties in comparison to its conformationally fluxional macrocyclic precursor.
