Abstract Methyl 2-[(cyanophenoxy)methyl]-3-furoates obtained from methyl 2-(chloromethyl)-3-furoate and salicylonitriles undergo tandem cyclization in the presence of excess t-BuOK in N,N-dimethylformamide (DMF) solution at 65°C to give substituted benzofuro[3,2-b]furo[2,3-d]pyridin-4(5H)-ones, derivatives of a novel heterocyclic system.
摘要 由 2-(氯甲基)-3-糠酸甲酯和水杨腈获得的 2-[(氰基苯氧基)甲基]-3-糠酸甲酯在过量 t-BuOK 的 N,N-二甲基甲酰胺 (DMF) 溶液中发生串联环化反应。 65°C 得到取代的苯并呋喃[3,2-b]呋喃[2,3-d]吡啶-4(5H)-酮,一种新型杂环系统的衍生物。
