A new three-component reaction, namely condensation-anti-Michael addition-aromatization, enables the construction of benzylic compounds. This reaction can not only act as an alternative approach to regioselective Csp2-H trifluoromethylation of arenes through...

A series of tunable iminiumions, generated in situ by the condensation of 4-trifluoromethyl-p-quinols with cyclic amines, can lead to the divergent synthesis of trifluoromethylated arylamines in a single step via redox-neutral isomerization. The direct α- and β-functionalization of saturated amines can be achieved regioselectively under mild conditions.
