Abstract
An effective synthetic method to achieve difluoromethylated oxazolidin-2-imine has been developed via visible-light promoted three-component tandem reaction of aryl allylamines, 2-BTSO2CF2H (BT = Benzothiazole) and isocyanates. This method features mild reaction conditions and good functional group tolerance, and the reaction mechanism was confirmed by experiments and interpreted by quantum chemical calculations.
