  Synthesis of β- and γ-Carbolines by the Palladium/Copper-Catalyzed Coupling and Cyclization of Terminal Acetylenes

  摘要：

  A variety of 3-substituted beta- and gamma-carbolines have been synthesized from N-substituted 3-iodoindole-2-carboxaldehydes and 2-bromoindole-3-carboxaldehydes, respectively. The coupling of these aldehydes with various terminal acetylenes with PdCl2(PPh3)(2)/CuI as the catalyst readily affords the corresponding alkynylindole carboxaldehydes, which have subsequently been converted to the corresponding tert-butylimines and cyclized to beta- and gamma-carbolines by either copper-catalyzed or thermal processes.

  Rapid Access to Novel 1,2,3-Triazolo-Heterocyclic Scaffolds via Tandem Knoevenagel Condensation/Azide–Alkyne 1,3-Dipolar Cycloaddition Reaction in One Pot

  摘要：

  An operationally simple, one-pot, two-step cascade method has been developed to afford biologically important fused 1,2,3-triazolo-heterocyclic scaffolds from 2-alkynyl aryl(heteroaryl) aldehydes and phenacyl azides. This unique atom economical transformation engages four reactive centers (aldehyde, alkyne, active methylene, and azide) under metal-free catalysis.

  Kabachnik–Fields reactions of various carbocyclic or heterocyclic acetylenic aldehydes together with subsequent Lewis acid catalyzed cyclizations have been studied. It was found that 5-exo-dig versus 6-endo-dig cyclization mode strongly depends on the structure of starting materials. Thus, nonaromatic acetylenic α-anilinomethylphosphonates underwent gold(III)-catalyzed or iodine-mediated 5-exo-dig

  研究了各种碳环或杂环炔醛的Kabachnik-Fields反应以及随后的路易斯酸催化的环化反应。发现5- exo - dig与6- endo - dig环化模式在很大程度上取决于起始材料的结构。因此，非芳族炔属α-苯胺基甲基膦酸酯经历了金（III）催化或碘介导的5- exo - dig环化成1 H-吡咯-2-基膦酸酯。与此相反，吸电子的杂芳族的基体构成通过专用6-含材料-1,2-二氢吡啶-2- ylphosphonate环内-挖闭环过程。仅对于含有苯环的α-氨基（2-炔基苯基）甲基膦酸酯，双环化是可能的。

  quinolines, dibenzofurans, and carbazoles. The precursors are heterocycles bearing a methyl ketone group ortho to an internal alkyne. They are commercially available or can be obtained in three to four classical and efficient reactions: Vilsmeier−Haack, Sonogashira (diversity point), Grignard, and Ley’s oxidation. Upon aminobenzannulation reaction—classical conditions being pyrrolidine neat or in a solvent

  强大的氨基苯甲酸酯化反应已用于合成氨基取代的喹啉，二苯并呋喃和咔唑。前体是带有与内部炔烃邻位的甲基酮基的杂环。它们可以商购获得，也可以通过三到四个经典有效的反应获得：Vilsmeier-Haack，Sonogashira（多样性点），Grignard和Ley's氧化反应。在进行氨基苯甲酸酯化反应时（典型的条件是纯净的吡咯烷或在溶剂中和4ÅMS的条件下），在某些情况下，随着烯胺的形成，会得到有趣的双取代喹啉，二苯并呋喃和咔唑。由于meta产生了取代的杂环，并且还不同于经典的杂环方法，经典的杂环方法是在含杂原子的环上进行封闭而不是形成苯环。

  Synthesis of azepino[4,5- b ]indole analogues via copper-catalyzed 7- endo -selective heteroannulation is reported. This strategy involves the Knoevenagel condensation of indole-1,2-alkynylaldehydes and isocyanoacetates, followed by copper-catalyzed 7- endo -selective annulation gives the product. This approach is applied towards the synthesis of the chromoazepinone core.
