The reactions of enaminones with dimethyl diazomalonate were investigated in the presence of copper(II) acetylacetonate. From the reaction of (E)‐3‐[methyl(phenyl)amino]‐1‐phenylprop‐2‐en‐1‐one (6c), dimethyl 2‐[methyl(phenyl)amino]‐4‐oxonaphthalene‐1,1‐(4H)‐dicarboxylate, was unexpectedly obtained as the major product. Quinoline derivatives were formed as the major products in the case of N‐methyl‐p‐anisidino
在乙酰丙酮铜(II)的存在下研究了烯胺酮与重氮丙二酸二甲酯的反应。从(E)-3- [甲基(苯基)氨基] -1-苯基丙-2-烯-1-酮(6c)与二甲基2- [甲基(苯基)氨基] -4-氧杂萘-1的反应中,出乎意料地获得了1-(4 H)-二羧酸盐作为主要产物。在N-甲基-对-茴香胺和N-甲基对-对甲苯胺烯酮的情况下,喹啉衍生物是主要产物。还实现了乙酰基烯胺酮的反应,并分离了喹啉衍生物作为主要产物。3 H-和5 H在这些反应中,二氢呋喃也作为副产物形成。这些结果与先前报道的关于叔烯胺酮与卡宾/金属卡宾的反应的结果不同。
