| Abstract: | A Zn(OTf)₂-mediated annulation of 2-amino-4H-chromen-4-one with diethyl acetylenedicarboxylate (DEAD) has been investigated to provide access to functionalized chromeno[2,3-b]pyrrole-2,3-dicarboxylate in excellent yields with good functional group tolerance. Furthermore, this method has also been used to synthesize a variety of novel annulated chromeno[2,3-b]pyrroles 3a-n through a plausible new mechanism. |
