A new PhI(OAc)2-mediated 1,2-aminohalogenation of prop-2-yn-1-yl carbamates and halogen sources is presented with excellent selectivity. The reaction is general for the construction of (E)-4-(halomethylene)oxazolidin-2-ones through the three-membered ring or N-radical.
一种新的PhI(OAc)2介导的prop-2-yn-1-yl carbamates和卤素源的1,2-氨基卤代反应被提出,具有优异的选择性。该反应对于通过三元环或N-自由基构建(E)-4-(卤代亚甲基)噁唑啉-2-酮具有普适性。
