Resolution and absolute configuration of 1,2,3,5,6,10bβ-hexahydro-6α-phenylpyrrolo[2,1-α]isoquinoline (McN-4612-Z). A problem of determination of the enantiomeric purity for a tertiary amine

Synthesis of chiral cyclic amines via Ir-catalyzed enantioselective hydrogenation of cyclic imines

A highly enantioselective hydrogenation of cyclic imines has been successfully realized providing chiral cyclic amines with excellent enantioselectivities in the absence of any additive.

The synthesis of isoquinoline alkaloid and its related compounds using alanine derivatives as chiral auxiliaries

Chiral 1-substituted isoquinoline derivatives, which were obtained by the reaction using alanine derivatives as chiral auxiliaries, were transformed to (S)-2,3,9,10,11-pentamethoxyhomoprotoberberine (7) and a synthetic intermediate for O-methylkreysigine (9) in good yields and high stereoselectivity. The corresponding chiral allyl derivative of isoquinoline was transformed to a pyrrolidinoisoquinoline (16) in a highly enantioselective manner.
