✦ Synopsis


Optically active y-and d-lactones are obtained by the hydrogenation of five-and six-membered cyclic anhydrides using a Ru(I1) complex with chiral phosphine ligand, DIOP, as a catalyst. Catalytic asymmetric hydrogenation with transition metal complexes has stereoselective addition of a hydrogen molecule to either of the prochiral faces of a double bond, such as C=C, C=O, and C=N, using transition metal complexes with chiral phosphine ligands as catalyst. Little was known about
