benzyl bromide 2 and cinnamyl bromide 3 give products which are dependent both upon the nature of the amine component of the enamine and, in the case of the amides, upon the amine from which the amide is derived. The β-enamino esters react with benzyl bromide to yield predominantly dialkylated products in the case of the pyrrolidine ester 1a. Reactions of the same esters with cinnamyl bromide yield
β-氨基丙烯酸酯(1-c)和酰胺(1d-o)与苄基溴2和肉桂基溴3的反应生成的产物既取决于烯胺的胺成分的性质,又取决于酰胺,从中衍生出酰胺的胺上。在吡咯烷酯1a的情况下,β-烯氨基酯与苄基溴反应,主要产生二烷基化产物。相同的酯与肉桂基溴的反应产生肉桂基和2-苯基丙烯基取代的甲酰基乙酸酯的混合物。烯氨基酰胺1d–f反应生成预期的烷基化衍生物。苯胺1i–o在苯胺氮上表现出亲核反应性。提出了导致观察到的产物的机制。
