A highly α-regioselective prenylation of imines enables the conversion a wide range of substrates including N- and C-aryl aldimines, N-alkyl aldimines, C-alkyl aldimines, and N- and C-aryl ketimines. The approach uses prenyl bromide as prenyl source and inexpensive zinc as mediator as well as environmentally benign 1,3-dimethyl-2-imidazolidinone (DMI) as solvent.
