Abstract
AbstractIn this paper, we report a novel sequential reaction sequence consisting of a series of processes including Sonogashira coupling, propargyl‐allenyl isomerization, [3+2] cycloaddition, denitrogenation, and highly selective biradical coupling reaction, providing an efficient synthesis of fused polycyclic pyrrole derivatives. The reaction features one CC bond and two CN bonds formed to construct the pyrrole unit, together with two rings efficiently assembled in one stroke.
