  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.

  general synthetic method for a wide range of medicinally useful 2-carboxylate derivatives of acridinols, quinolinols, and naphthalenols has been developed via silver-catalyzed electrophilic cyclization of 3-(2-alkynyl)aryl-β-ketoesters. The designed reaction involved selective C–C bond formation on more electrophilic alkynyl carbon, which resulted in the regioselective 6-endo-dig cyclized product, as confirmed

  Published as part of the Special Topic Recent Advances in Amide Bond Formation Abstract A post-Passerini condensation transformation can be employed in the synthesis of three types of amides: α-hydroxy, α-oxy, and α-oxo amides. K2CO3 efficiently promotes the solvolysis of α-acetoxy amides to form α-hydroxy amides in methanol. 2-Acetoxy-2-(2-alkynyl­quinolin-3-yl)acetamides in basic methanol are cyclized

  作为特别主题的一部分发表，酰胺键形成的最新进展 抽象 Passerini后缩合转化可用于合成三种类型的酰胺：α-羟基，α-氧基和α-氧代酰胺。K 2 CO 3有效地促进α-乙酰氧基酰胺的溶剂分解以在甲醇中形成α-羟基酰胺。碱性甲醇中的2-乙酰氧基-2-（2-炔基喹啉-3-基）乙酰胺通过脱乙酰基作用和5- exo - dig环化作用环化为1,3-二氢呋喃[3,4- b ]喹啉-1-羧酰胺。在碱性介质中用I 2处理2-羟基-2- [2-（苯基乙炔基）喹啉-3-基]乙酰胺产生吡咯并[2,3- b]喹啉-2,3-二酮。该环化涉及分子内环化，脱炔基芳构化和仲醇的氧化。
