Diarylmethylamines are of great interest due to their prevalence in pharmaceutical chemistry. As a result, new methods for their synthesis are in demand. Herein, we report a versatile protocol for the synthesis of diarylmethylamine derivatives involving palladium-catalyzed arylation of in situ generated 2-azaallyl anion intermediates. The 2-azaallyl anions are generated by reversible deprotonation of readily available aldimine and ketimine precursors. Importantly, the arylated aldimine and ketimine products do not undergo isomerization under the reaction conditions. Scale-up of the arylation and hydrolysis of the resulting products to furnish diarylmethylamines were also successfully performed. This journal is the Partner Organisations 2014.

Page/Page column 55; 65, (2008/12/04)
The present application relates to novel methods for the preparation of primary, secondary and tertiary carbinamine compounds, particularly the preparation of compounds of formulae I, IV and VI, from a carbonyl compound of formula II in the presence of ammonia or an ammonium equivalent of the formula NH4+X-, by way of allylation, crotylation, arylation, reductive amination and catalytic hydrogenation.
