Özet

In this paper, we report the efficient and regioselective synthesis of 2-aminopyrrole-4-carboxylates as derivatives of conformationally restricted analogues of gamma-amino butyrates (GABA) via a zinc perchlorate catalyzed amination-annulation of alpha-cyanomethyl-beta-ketoesters under mild reaction conditions in water.
