2-Oxotetrahydropyridines and 2-oxo-octahydroquinolines have been isolated from the reaction of acryloyl chloride with imines, together with the enamide and, in some cases, the amide. Crotonoyl and cinnamoyl chlorides give mixtures consisting mainly of the enamides. 2-Oxotetrahydropyridines and 2-oxo-octahydroquinolines have also been isolated from the reaction of acrylic acid with imines. The mechanisms
从丙烯酰氯与亚胺,烯酰胺以及某些情况下的酰胺的反应中已经分离出2-氧四氢吡啶和2-氧八氢喹啉。巴豆酰氯和肉桂酰氯产生主要由烯酰胺组成的混合物。还已经从丙烯酸与亚胺的反应中分离出2-氧代四氢吡啶和2-氧代八氢喹啉。讨论了这些反应的机理。
