The preparation of important pharmaceutically active highly branched tertiary amines by the reaction of Grignard reagents with adducts of cyclic ketones, benzotriazole (or pyrazole) and secondary amines is far superior to previously available routes.
Enamines derived from cyclohexanone, propionaldehyde, and n-butyraidehyde and secondary amines react with pyrrole and pyrazole, affording new Michael type adducts respectively.
