The asymmetric total synthesis of (S)-isocorydine, a potential drug for the cure of hepatocellular carcinoma, is described. Asymmetric transfer hydrogenation of 3,4-dihydroisoquinoline using a chiral Ru(II) catalyst was applied to the synthesis of isocorydine as the key step, in which the ee value achieved is up to 99%. The overall yield is 9.4% after 12 synthetic procedures.
