  A process for preparing an N-acyltetrahydro­isoquinoline represented by formula (II) wherein A repesents a phenylene ring substituted with a hydroxyl group, a Cl-4 alkoxy, acetoxy, or benzyloxy group; R represents a hydrogen atom, a Cl-1 alkyl, or phenyl group; and X represents a hydrogen atom, a phenyl group, or a phenyl group substituted with a hydroxyl group, a lower alkoxy group or an acetoxy group, which comprises asymmetrically hydrogenating a solution of an N-acyl-1-­methylenetetrahydroisoquinoline or N-acyl-1-benzylidene­tetrahydroisoquinoline represented by formula (I) wherein A, R, and X are as defined above, in solution at a H₂ pressure of 1 to 10 kg/cm² at 10 to 40°C for 10 to 160 hours, in the presence as catalyst of an optically active ruthenium-phosphine complex, of which several examples are given. The process exclusively and efficiently provides a useful isomer of the N-actyltetrahydroisoquinoline of high purity which is useful as an intermediate for synthesizing isoquinoline type alkaloids as pharmaceuticals without involving optical resolution of a racemate.

  In the presence of a small amount of RuX(2)[(R)- or (S)-BINAP] (X = anionic ligand) a wide range of (Z)-2-acyl-1-benzylidene-1,2,3,4-tetrahydroisoquinolines are hydrogenated to give the saturated products in nearly quantitative yields and in high (up to 100 %) optical yields. The enamide substrates are selectively prepared by N-acylation of the corresponding 1-benzylated 3,4-dihydroisoquinolines under suitable acylation conditions; some crystalline materials having low solubility are obtained by a second-order Z/E stereomutation technique utilizing the double-bond photolability and lattice energy effects. This asymmetric hydrogenation sets the key stereogenic center in a predictable manner, either R or S flexibly, at the C(1) position of the benzylated tetrahydroisoquinolines. The chiral products are converted by standard functional group modification to tetrahydropapaverine, laudanosine, tretoquinol, norreticuline, etc. Hydrogenation of the simple 1-methylene substrate is used fbr synthesis of salsolidine. This enantioselective hydrogenation is applied to the synthesis of morphine and its artificial analogues such as morphinans and benzomorphans of either chirality. A mnemonic device is presented for predicting the reactivity and enantiofacial selection of the BINAP-Ru catalyzed hydrogenation. Reaction with BINAP-Rh catalyst proceeds with a lower enantioselectivity and an opposite sense of asymmetric induction.
