Particularly picky ligands! An efficient (S/C, substrate/catalyst, up to 500) Rh‐catalyzedenantioselectiveaddition of arylboronicacids to 2‐nitrostyrenes under mild conditions was developed, which gave excellent yields (up to 99 %) and enantioselectivities (up to 98 % ee) by using tert‐butanesulfinylphosphine as a ligand (see scheme). Based on this method, (R)‐cherylline was synthesized in 70 %
