Literature data on the title reactions are reviewed and further examples given particularly with dialkylhydrazines and hydrazones. Compounds derived from 2-ethoxycarbonyl-4,6-diphenylpyrylium tend to cyclise and new examples of the dihydropyrazoloquinoline (27) and oxidopyrido[1,2-b]pyridazinium [(62)–(64)] ring systems are described.
综述了标题反应的文献数据,并给出了特别是二烷基肼和的其他实施例。衍生自2-乙氧基羰基-4,6-二苯基吡啶鎓的化合物容易环化,并描述了二氢吡唑并喹啉(27)和氧化吡咯并[1,2- b ]吡啶鎓[(62)–(64)]环系的新实例。
