pathway for the enantioselective synthesis of benzylisoquinoline alkaloids. The key steps of the synthesis of (+)-(S)-laudanosine (1) and (–)-(S)-xylopinine (2) are a Sonogashira coupling that builds up the C1–C8a bond of the benzylisoquinoline skeleton, an intramolecular Ti-catalyzed hydroamination of an alkyne, and a subsequent enantioselective imine reduction according to Noyori’s protocol.

该研究为苄基异喹啉生物碱的对映选择性合成提供了一条新途径。合成 (+)-(S)-laudanosine (1) 和 (-)-(S)-xylopinine (2) 的关键步骤是建立苄基异喹啉骨架的 C1-C8a 键的 Sonogashira 偶联,根据 Noyori 的协议,分子内 Ti 催化的炔烃加氢胺化,以及随后的对映选择性亚胺还原。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
