best: The title reaction has been achieved by asymmetric rhodium catalysis employing an extremely simple, chiral N‐(sulfinyl)cinnamylamine ligand. A variety of highly enantioenriched, tertiary α‐hydroxy carbonyl derivatives were easily accessed at room temperature under mild conditions with enantioselectivities of up to 99 %.
