  Pyrano[4,3-b]quinolines Library Generation via Iodocyclization and Palladium-Catalyzed Coupling Reactions

  摘要：

  Synthesis of a 80-member library of novel pyrano[4,3-b]quinoline in solution-Phase is reported. The key intermediate, 4-iodopyrano[4,3-b]quinolines were synthesized by the electropHic iodocyclization of corresponding oho-alkynyl ' aldehydes in good to excellent yields under mild reaction,conditions. Subsequently a diverse set of libraries was generated by employing palladium:catalyzed Suzuki-Miyauta, Heck, and Sonogashira coupling reactions on 4-iodopyrano[4,3-b]quinolines. In this:way,- a series of structurally different and biologically interesting molecules were obtained. Some of the selected compounds were screened against 3D7 strains of Plasmodium falciparum for antimalarial activity. Suzuki coupling products 6{3} and 6{21} and Heck coupling product 8{12} exhibit promising antimalarial activity.

  amination of ortho‐alkynyl quinoline/pyridine aldehydes using N‐fluorobenzenesulfonimide as nitrogen source under mild reaction conditions has been described. The designed reaction strategy was triggered by trapping of fluorine by base with subsequent attack of bis(phenylsulfonyl)‐λ2‐azane on the carbonyl carbon of a heterocycle, which was gradually converted into the corresponding amine through a Curtius

  本文描述了一种无金属，多功能的三键定向方法，该方法在温和的反应条件下，使用N-氟苯磺酰亚胺作为氮源，对邻炔基喹啉/吡啶醛进行脱羰CH-氨基化。所设计的反应策略通过用碱与双（苯基磺酰基）随后攻击-λ捕集氟的触发2 -azane上的杂环，其逐渐通过库尔提斯重排型转化成相应的胺的羰基碳。该方案提供了一步一步的方法，可将醛以高收率转化为胺。合成的胺已成功转化为生物学上重要的吡咯并喹啉/吡啶。

  A regioselective tandem approach for annulated napthyridines/isoquinolines embedded with the phosphine oxide group under mild reaction conditions has been achieved in good to excellent yields. The designed strategy involves the triflate-induced formation of new C sp3–P and C sp2–N bond formation in one pot. This protocol was also well tolerated for the construction of densely functionalized organo-phosphorylated
