An optically active l-hydroxymethyl-substituted tetrahydroisoquinoline alkaloid, (S)-calycotomine 1, was conveniently synthesized by using catalytic asymmetric hydrogenation of 1-benzyloxymethyl-3,4-dihydro-6,7-dimethoxyisoquinoline 6 with 0.5 mol % of an iridium(I) complex of (R)-BINAP in the presence of 3,4,5,6-tetrafluorophthalimide.
