  The Stetter procedure has been adapted to produce oligomeric and polymeric pyrrolylpyridines, which have been characterised by 13C NMR spectroscopy. The lower activity of 2-(pyrrol-2-yl)pyridines towards quaternisation permits selective N-alkylation of 2-, 3- and 4-(pyrrol-2-yl)pyridines.

  Stetter程序已经过调整，可以生产低聚和聚合的吡咯基吡啶，这些化合物已通过13 C NMR光谱进行了表征。2-（吡咯-2-基）吡啶对季铵化的较低活性允许2-，3-和4-（吡咯-2-基）吡啶的选择性N-烷基化。
