Abstract Thirty N-substituted Hantzsch 1,4-dihydropyridines were prepared under mild and neutral conditions from N-substituted enaminocarbonyl derivatives and aldehydes activated under the form of N-(1-chloroalkyl)pyridinium chlorides by means of thionyl chloride and pyridine. The scope of the method is discussed.
摘要 在温和和中性条件下,以N-(1-氯烷基)吡啶氯化物形式活化的N-取代烯氨基羰基衍生物和醛,通过亚硫酰氯和吡啶制备了30个N-取代Hantzsch 1,4-二氢吡啶。讨论了该方法的范围。
