A very simple domino reaction under solvent-free conditions of various pyridine-like heterocycles with 1,2-diaza-1,3-dienes produces in good yields imidazo[1,2-a]pyridines, imidazo[1,2-a]quinolines, and imidazo[2,1-a]isoquinolines. The advantage of this one-pot transformation lies in the use of simple pyridine-like compounds without prefunctionalization of the starting heterocycles.
在无溶剂条件下，各种吡啶类似物与 1,2-二氮杂-1,3-二烯的非常简单的多米诺反应以良好的收率生成咪唑并[1,2-a]吡啶、咪唑并[1,2-a]喹啉和咪唑并[2,1-a]异喹啉。这种一锅转化的优点在于使用简单的吡啶类似物，而无需对起始杂环进行预官能化。
