we found a novel approach to the simple and practical synthesis of 3-aminopyrrolederivatives through the four-component coupling reaction of a functionalized silane, a nitrile, an aldehyde, and trimethylsilyl cyanide by Yb(OTf) 3 -catalyzed annulation of a 2-azabutadiene with trimethylsilyl cyanide. In this paper, we also disclose a single-step transformation of the 3-aminopyrrole framework into the
