Mr. Ebden et al., ACTIVATION OF BENZYLIC AMINES TOWARDS REGIOSELECTIVE METALATION BY BORANE COMPLEX-FORMATION, Tetrahedron letters, 36(47), 1995, pp. 8697-8700
Formation of borane complexes of N, N-dimethylbenzylamine 4 and N-meth
yltetrahydroisoquinoline 1 facilitates regioselective metallation of t
hese systems using BuLi, giving benzylic anions which react with a ran
ge of electrophiles.
