    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.

    N-carbamoyl-β-arylethylamines with diverse aldehydes toward enantioenriched THIQs. The obtained products proved to be competent intermediates in the synthesis of THIQ, aporphine, tetrahydroberberine, morphinan, and androcymbine natural products. Novel catalyst design with regard to the stabilization of cationic intermediates was crucial to accomplish high reactivity while simultaneously achieving unprecedented
    四氢异喹啉 (THIQ) 生物碱是一大类生物活性天然产物,其母体化合物和相关的下游生物合成次级代谢物跨越数千个孤立的结构。针对相关 THIQ 的化学酶合成方法依赖于 Pictet-Spenglerase,例如去甲克劳林合成酶 (NCS),其范围严格限于与多巴胺相关的酚类底物。为了克服化学合成背景下的这些限制,我们在此报告了N的不对称 Pictet-Spengler 反应-氨基甲酰基-β-芳基乙胺与不同的醛对对映体富集的 THIQ。所得产物证明是合成THIQ、阿吗啡、四氢小檗碱、吗啡喃和雄仙碱天然产物的有效中间体。关于阳离子中间体稳定化的新型催化剂设计对于实现高反应性至关重要,同时实现生物相关底物反应的前所未有的立体选择性。

    AbstractA method is described for the preparation of (R)‐ and (S)‐2‐ethoxycarbonyl‐1‐formyl‐6,7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline involving a Swerntype oxidation of (R)‐ and (S)‐2‐ethoxycarbonyl‐1‐hydroxymethyl‐6, 7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline (R)‐ and (S)‐2‐(ethoxycarbonyl)calycotomine}. The utility of these aldehydes in asymmetric synthesis of isoquinoline alkaloids has been demonstrated by their conversion into (S)‐ and (R)‐xylopinine, respectively; also, the (R)‐aldehyde has been employed for the synthesis of (8S,14S)‐coralydine.
