stereoselective synthesis of highly substituted α-haloenamides was described via the zinc halide mediated direct addition of benzhydryl halides to ynamides under mild conditions. The products α-haloenamides were further transformed into multisubstituted enamides via Suzuki and Sonogashira cross-coupling reactions.
在温和条件下,通过卤化
锌介导的苯甲基卤化物直接加成到酰胺中,描述了高度取代的α-卤代烯酰胺的区域和立体选择性合成。通过Suzuki和Sonogashira交叉偶联反应,将产物α-卤代烯酰胺进一步转化为多取代的酰胺。
