A system for the directed hydrogenation of nitrogen heterocycles is described in which hydrogen is delivered cis to a hydroxymethyl group by a rhodium catalyst with a simple phosphine ligand. The chemistry is applied to the synthesis of the hygric ac

A new chiral phosphine–olefin ligand (S)-1 has been designed and synthesized from l-hydroxyproline via a short reaction sequence. It was examined for its efficiency in the rhodium-catalyzed asymmetric addition of arylboronic acids and a phenylzinc
