  Tandem Synthesis of Pyrroloacridones via [3 + 2] Alkyne Annulation/Ring-Opening with Concomitant Intramolecular Aldol Condensation

  摘要：

  An efficient cascade strategy for the direct synthesis of pyrrolo[3,2,1-de]acridones 4a-v, 5a-h from iodopyranoquinolines 2a-i by the palladium-catalyzed regioselective [3 + 2] alkyne annulation/ring-opening followed by intramolecular aldol condensation under microwave irradiation is described. The chemistry involves the in situ formation of pyrroloquinolines Y, via palladium-catalyzed selective [3 + 2] annulation of iodopyranoquinolines and internal akynes with ring-opening and successive intramolecular cross-aldol condensation. Both the symmetrical and unsymmetrical internal alkynes were reacted smoothly to provide the desired pyrroloacridones in good yields. This methodology provides the facile conversion of easily accessble iodopyranoquinoline into highly functionalized biologically important pyrroloacridones in a single process.

  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。
