Going forward, a potential library of donor-acceptor cyanoarene-based chiral photocatalysts can be envisioned to tailor the photophysical properties of the catalysts to the reactions. A possible potential pathway to modulate the enantioselectivity of these catalysts is the introduction of only one photocatalyst unit (PC) and replacement of the second photocatalyst unit with a bulky group that better extends the chirality of the BINOL backbone into the substrate-binding pocket of the chiral phosphoric acid (Scheme 8-R 1 ). Further, enantioselectivity might be improved by increasing the acidity of the phosphoric acid through conversion to the N-triflyl phosphoramide (Scheme 8-R 2 ). We believe that this new class of highly modular catalysts will help open new avenues of research in chiral photocatalysis.
