A Photocatalytic Regioselective Hydroaminoalkylation of Aryl-Substituted Alkenes with Simple Amines


A photocatalytic method for the alpha-selective hydroaminoalkylation of cinnamate esters has been developed. The reaction involves the regioselective addition of alpha-aminoalkyl radicals generated from aniline derivatives or aliphatic amines to the alpha-position of unsaturated esters. The scope of aromatic alkenes was extended to styrenes undergoing hydroaminoalkylation with anti-Markovnikov selectivity, which confirms the importance of the aromatic group at the beta-position. Simple scale-up is demonstrated under continuous-flow conditions, highlighting the practicality of the method.
