Ceric ammonium nitrate efficiently catalyzes the aza-Michael reaction of amines with α,β-unsaturated carbonyl compounds in water to produce the corresponding β-amino carbonyl compounds in very good yields under mild conditions. The reaction is procedurally simple and offers limited chemoselectivity, as aromatic amines were found to be unreactive.
