Formation of borane complexes of N,N-dimeihylbenzylamine, N,N-dimethyl
(1-naphthyl)methylamine, N,N-dimethyl(2-naphthyl)methylamine, N -methy
ltetrahydroisoquinoline and N-methylisoindoline facilitates regioselec
tive metallation of these systems using BuLi, giving intermediate benz
ylic anions which react with a range of electrophiles to give products
in good yield. (C) 1998 Elsevier Science Ltd. All rights reserved.
