Furopyridines have a wide spectrum of biological activity [1 3] and some of them are used in medicine [4], thus stimulating a search for biologically active compounds among the derivatives of a new heterocyclic system, pyrano[4,3d]furo[2,3-b]pyridine. Synthesis was performed on the basis of 3-phenacyloxy-4-cyanopyrano[3,4-c]pyridines ( I a u) obtained earlier [5]. The presence of an active methylene
呋喃吡啶具有广泛的生物活性 [1 3],其中一些用于医学 [4],从而刺激了在新的杂环系统吡喃并[4,3d]呋喃 [2] 的衍生物中寻找具有生物活性的化合物,3-b]吡啶。在之前获得的 3-phenacyloxy-4-cyanopyrano[3,4-c] 吡啶 (I au) 的基础上进行合成 [5]。这些化合物中活性亚甲基的存在使得在乙醇钠存在下进行分子内环化成为可能,产生 9-氨基吡喃并[4,3-d]呋喃[2,3-b]吡啶(II au) .
