In(OTf)₃-catalyzed reorganization/cycloaddition of two imine units and subsequent modular assembly of acridinium photocatalysts.

2 Cycloaddition manipulation between N -aryl imines and dienophiles is defined as the Povarov reaction, an extremely significant part of the Diels–Alder reaction, which has benefited academia and industry because of the powerful capability of preparing widely utilized nitrogen-containing cycles. 3 Although numerous marvellous reactions have been discovered in this realm over the past decades, this type of cycloaddition appea
