studies towards a small molecule catalytic approach to access atropisomeric diaryl ethers that proceeds via a C(sp2)-H alkylation using nitroalkanes as the alkyl source. A quaternary ammonium salt derived from quinine containing a sterically hindered urea at the C-9 position was found to effect atroposelective C(sp2)-H alkylation with moderate to good enantioselectivities across several naphthoquinone-containing
