Diastereoselective synthesis of cis-cyclopentane-1,2-diamine derivatives via organophotoredox-catalyzed [3 + 2] cycloadditions

An efficient way to access diverse cis -cyclopentane-1,2-diamines was developed based on organophotoredox-catalyzed [3 + 2] cycloadditions between cyclopropylamines and N -vinylphthalimides.
