novel gold-catalyzed tandem cycloisomerization/hydrogenation of chiral homopropargyl sulfonamides has been developed. Various enantioenriched pyrrolidines can be obtained in excellent yields and excellent enantioselectivities by combination of chiral tert-butylsulfinimine chemistry with gold catalysis. Importantly, this represents the first example of a pyrrolidine synthesis from homopropargyl sulfonamide
已经开发了一种新型的金催化的手性高炔丙基磺酰胺的串联环异构化/氢化反应。通过手性叔丁基亚磺酰亚胺化学与金催化的结合,可以以优异的产率和优异的对映选择性获得各种对映体富集的吡咯烷。重要的是,这代表了由高炔丙基磺酰胺合成吡咯烷的第一个例子。
