A novel copper-catalyzed aminobromination-elimination process has been developed, which provides an easy access to α,β-unsaturated vicinal haloamindes derivatives from readily available α,β-unsaturated ketones and esters in good to excellent yields. The isolated intermediate discloses that the current system proceeds through the aminobromination process.
已经开发了一种新颖的铜催化的氨基溴化消除方法,该方法可以容易地从容易获得的α,β-不饱和酮和酯中以良好的产率获得α,β-不饱和的邻位卤代氨基甲酸酯衍生物。分离的中间体公开了当前系统通过氨基溴化过程进行。
