The synthesis of 3-methyl- and 3,4-dimethyltetrahydroisoquinolines from aromatic aminoalkenes using intramolecular hydroamination reactions is described. This reaction was achieved by way of a reductive aminomercuration using mercuric acetate followed by sodium borohydride, or by using sub-stoichiometric amounts of n-butyllithium.
