Abstract

Systematic changes, first to the structure of the catalyst scaffold and then to the ligating groups, are used to fine tune supramolecular catalysts to achieve high regioselectivity (95–98%) and high enantioselectivity (94–97% ee) across a series of meta-substituted styrenes varying in electronic character.
