A mild three-component reaction of aromatic aldehydes, alkyl bromides, and aqueous ammonia as the nitrogen source gives imines in very good yields. The reaction conditions are compatible with a range of functional groups. The reaction of aldehydes and aqueous ammonia with epoxides leads to imines bearing a vicinal hydroxyl group regioselectively.
