An efficient and convenient procedure is described for the preparation of N3-functionalized aminoimidazolines and aminopyrimidines through the aza-Michael additions of aminoimidazolines and aminopyrimidines with α, β-unsaturated carbonyl compounds catalyzed by KF/Al2O3. This method offers a novel and efficient protocol for the N3-functionalized aminoimidazolines and aminopyrimidines with good regioselectivity and high purity under mild conditions.
