Asymmetric hydrogenation: The title reaction provides an efficient and rapid access to chiral 1‐ and 3‐substituted 1,2,3,4‐tetrahydroisoquinolines with excellent enantioselectivity (see scheme; L=ligand). A preliminary mechanistic study indicates that the 1,2‐hydride addition might be the initial step in the reaction. The method has been used in the synthesis of urinary antispasmodic drug (+)‐solifenacin
不对称氢化:标题反应可高效且快速地获得手性1和3-取代的1,2,3,4-四氢异喹啉,且具有出色的对映选择性(参见方案; L =配体)。初步的机理研究表明,添加1,2-氢化物可能是反应的第一步。该方法已用于尿解痉药(+)-索非那新的合成。
