  催化不对称 Pictet-Spengler 平台作为天然生物碱的仿生多样化策略

  摘要：

  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。

• Concise and Diversity-Oriented Route toward Polysubstituted 2-Aminoimidazole Alkaloids and Their Analogues

  Alkaloids of the naamine family were synthesized from diverse propargylamines in just two steps (see scheme: R1=Me, R2=substituted benzyl, R3=Ar). Thus, the addition to a propargylamine of a carbodiimide generated in situ, silver(I)‐catalyzed intramolecular hydroamidation, and subsquent deprotection provide access to the heterocyclic core of numerous natural products and biologically active compounds

  纳胺家族的生物碱仅需两个步骤就可以由多种炔丙基胺合成（参见方案：R 1 = Me，R 2 =取代的苄基，R 3 = Ar）。因此，除了在炔丙基胺中原位生成的碳二亚胺之外，银（I）催化的分子内加氢酰胺化作用以及随后的脱保护作用也使人们可以接近许多天然产物和生物活性化合物的杂环核。Boc =叔丁氧羰基，Cbz =碳苄氧基。

  Bioactivity-guided phytochemical investigation on 70% aqueous acetone extracts of the twigs and leaves of Horsfieldia kingii led to the isolation of two novel cyclic diarylpropanes (1 and 2) bearing a 2,3-dihydro-1H-indene core, one new diarylpropane (3), six known diarylpropanes (4-9), one flavanol (10), and seven lignans (11-17). Their structures were determined by extensive spectroscopic analysis, electronic circular dichroism calculations, and X-ray diffraction crystallography. Moreover, a biomimetic synthesis of 1 and 2 were accomplished in four steps. The in vitro nitric oxide production inhibition tests of these compounds revealed that compounds (+/-)-2, (+)-2, (-)-2, and 10 were potential with IC50 values lower than 10 AM. Compound 2 could inhibit iNOS expression in LPS-induced RAW264.7 cells at a series of non-cytotoxic concentrations (<20 mu M). Furthermore, the bioassay results also suggested the primary SARs of 1-phenyl-2,3-dihydro-1H-indene based scaffold. (C) 2020 Elsevier Ltd. All rights reserved.
• Strategies for the construction of morphinan alkaloid AB-rings: regioselective Friedel-Crafts-type cyclisations of γ-aryl-β-benzoylamido acids with asymmetrically substituted γ-aryl rings

  The regioselectivity of the Friedel-Crafts-type cyclisation of a range of gamma-aryl-B-benzoylamido acids, bearing oxy substituents at the C(3)- and C(4)-positions of the gamma-aryl ring, has been investigated. In all of the cases examined (with 3,4-dimethoxy, 3,4-methylenedioxy and 3-hydroxy-4-methoxy substituents) the Lewis acid promoted cyclisation proceeds with exclusive regioselectivity for attack at the C(6)-position rather than at the C(2)-position, and furnishes the corresponding N- and O-protected 3-amino-6,7-dihydroxy-1-tetralone derivatives. This inherent regioselectivity can be overturned by the regioselective introduction of chlorine as a blocking group for the C(6)-position; subsequent Lewis acid promoted cyclisation then proceeds with exclusive regioselectivity for attack at the C(2)-position to deliver the corresponding N- and O-protected 3-amino-5-chloro-7,8-dihydroxy-1-tetralone derivative. These complementary cyclisation protocols represent useful methods for the preparation of these benzo-fused carbocyclic ring systems, which are the functionalised AB-rings of a range of morphinan alkaloids.
