Abstract
Particularly picky ligands! An efficient (S/C, substrate/catalyst, up to 500) Rh-catalyzed enantioselective addition of arylboronic acids 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 % overall yield. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
