Expedient Ni(OTf)2/visible light photoredox-catalyzed annulation of donor–acceptor cyclopropanes with cyclic secondary amines

The annulative coupling of donor-acceptor cyclopropanes with cyclic secondary amines is reported using the combination of Ni(OTf)2 and visible light assisted eosin Y catalysis for tandem C-N and C-C bond formation. The reaction sequence provides a potential synthetic tool for the construction of pyrrolotetrahydroisoquinolines.
