Addition of the D-camphor imine of benzylamine to a variety of aldehydes or ketones gives diastereoselectivites ranging from 16-70percent.The d.e. value is attributed by the difference of the orientation of C-11 groups.The rotation of (5e) indicates that addition reaction occurs from the pro-R face of lithium derivative (2).

The reactions of benzylidenebenzylamine with methyllithium and lithium diethylamide were investigated by GLC.Products with different structures from condensation of the azomethine are formed: Cyclic 2,4,5-triphenyl-3-benzylimidazolidine and noncyclic dibenzylidene-1,2-diphenylethylenediamine.Investigation of the effects of the solvent, temperature, and ratio of reagents on the reaction made it possible to obtain conditions for synthetic application of the 1,3-diphenylazaallyllithium, obtained by metallation of benzylidenebenzylamine, in reactions with alkyl halides, carbon dioxide, carbonyl compounds, and phenyl isocyanate.These conditions involve a temperature between -60 and -70 deg C and an equimolar ratio between the reagents.
