报道了碳酸铯促进的N-(8-氨基喹啉)-3-丁烯酰胺的氢氰化反应, 以8-氨基喹啉作为导向基团保护的3-丁烯酸为原料, 与三甲基硅氰在90 ℃下进行反应, 得到了一系列3-氰基丁酰胺衍生物. 机理研究表明, 该反应为双键的亲核加成反应而非自由基反应.

关键词: 烯烃, 氢氰化反应, 碳酸铯, 三甲基硅氰, 3-氰基丁酰胺

A novel Cs2CO3-promoted hydrocyanide reaction of the directing group-protected N-(quinolin-8-yl)but-3-enamides with trimethylsilyl cyanide to afford 3-cyanobutylamides is described. Mechanistic studies have shown that this reaction is a nucleophilic addition reaction of double bonds rather than a free radical reaction.

Key words: olefin, hydrocyanation reaction, cesium carbonate, trimethylsiyl cyanide, 3-cyanobutylamide
