  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.

  An efficient strategy for the synthesis of pyrrolo[1,2-a]quinolines and indolizines from pyranoquinolines via site-selective electrophilic cyclization and subsequent opening of pyran ring using silver/iodine under mild reaction conditions is described. This approach involves the preferential attack of the pyridyl nitrogen over aryl ring and leads to the formation of 5-endo-dig cyclized products. Quantum

  The chemoselective synthesis of functionalized azido- and triazolo-containing nitrogen heterocycles using sodium azide and o-alkynylaldehydes has been described. The azidation reaction was preferred in acetonitrile while the [3 + 2]-cycloaddition was favored in DMSO. Furthermore, the azido-pyranoquinolines were employed for the synthesis of benzonaphthyridines via the Staudinger reaction at room temperature

Mechanistic studies confirm the formation of azido-pyranoquinolines through nucleophilic attack of azide on pyrilium intermediate over [3 + 2] cycloaddition of the azide on the alkyne. The synthesized azido-pyranoquinolines were transformed into benzonaphthyridines via Staudinger reaction. The mechanistic pathway was supported by deuterium labeling experiment and X-ray crystallographic
