  A Novel Method for N3-Functionalized Aminoimidazolines and Aminopyrimidines by Aza-Michael Additions of Aminoimidazolines and Aminopyrimidines to α,β-Unsaturated Carbonyl Compounds

  摘要：

  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 alpha, beta-unsaturated carbonyl compounds catalyzed by KF/Al(2)O(3). This method offers a novel and efficient protocol for the N3-functionalized aminoimidazolines and aminopyrimidines with good regioselectivity and high purity under mild conditions.
