  摘要：

  本发明揭示了具有以下结构式的取代苯并吡喃[3,4-c]吡啶：##SPC1## 在上述结构式中，R.sub.1和R.sub.2分别为氢、羟基或1至6个碳原子的较低烷氧基；X为氧原子、硫原子、甲基基团或由氢、1至6个碳原子的较低烷基基团或1至6个碳原子的较低烷酰基基团取代的氮原子。本发明的化合物是通过在酸催化剂存在下将R.sub.1、R.sub.2-取代酚与3-羧乙氧基-4-哌啶酮反应制备的，得到中间体R.sub.1、R.sub.2-取代苯并吡喃[3,4-c]吡啶。通过用适当取代的烷基卤化物处理苯并吡喃[3,4-c]吡啶，可以获得N-氨基烷基苯并吡喃[3,4-c]吡啶。本发明的化合物可用作治疗支气管哮喘的支气管扩张剂。

  Substituted benzopyrano[3,4-c]pyridines having the following structural formula are disclosed: ##SPC1## In the above formula, R.sub.1 and R.sub.2 are hydrogen, a hydroxyl group or a lower alkoxyl group of from 1 to 6 carbon atoms; R.sub.3 is hydrogen or a lower alkyl group of from 1 to 6 carbon atoms and X is an oxygen atom, a sulfur atom, a methylene group or a nitrogen atom substituted by hydrogen, a lower alkyl group of from 1 to 6 carbon atoms or a lower alkanoyl group of from 1 to 6 carbon atoms. The compounds of this invention are prepared by reacting an R.sub.1, R.sub.2 -substituted phenol with a 3-carbethoxy-4-piperidone in the presence of an acid catalyst to give an intermediate R.sub.1, R.sub.2 -substituted benzopyrano[3,4-c]pyridine. N-aminoalkylbenzopyrano[3,4-c]pyridines are obtained by treating the benzopyrano[3,4-c]pyridine with an appropriately substituted alkyl halide. The compounds of this invention are useful as bronchodilators for the treatment of bronchial asthma.
