The recent advances of the visible-light-mediated photocatalytic cleavage of C–C and C–N bonds associated with amines and their derivatives, which featuring mild conditions, unique selectivity, broad substrate scope and green manner, are reviewed.
A visible-light-induced cycloaddition between 2-alkenylarylisocyanides and cyclopropylanilines to afford 3-aminotetrahydro-1H-carbazols with high atom and step economy has been realized.
Cyclopropylamine synthesis: using halomethyl radicals as the CH2 source, photoredox-catalysed cyclopropanation of N-vinylimides could proceed well, giving modular access to 1- or 2-arylcyclopropylamines.
A mild and efficient method for photoredox-catalyzed bromonitroalkylation of alkenes is described herein.
A photocatalyst- and additive-free multi-component reaction driven by cyclopropylamine-based EDA complex has been developed to access cyclopentylamines under water medium conditions.
