Palladium(II)-catalyzed aerobic oxidative cyclization of alkenes with tethered tert-butanesulfinamides furnishes enantiopure 2,5-disubstituted pyrrolidines, originating from readily available and easily diversified starting materials. These reactions are the first reported examples of metal-catalyzed addition of sulfinamide nucleophiles to alkenes.
钯(II)催化的烯烃与带支链叔丁基亚磺酰胺的有氧氧化环化反应,提供了手性纯的 2,5-二取代吡咯烷,源于易得且易于多样化的起始原料。这些反应是首例报道的金属催化亚磺酰胺亲核试剂与烯烃加成的例子。
