Abstract
Herein, we found that treating N-substituted pyrrole-2-carboxaldehydes with arylalkenes in DMF in N2 at 120 °C could afford pyrrolidine scaffolds with an up to 85% yield. This approach has several remarkable features, such as atom and step economy, readily accessible raw materials, and easy-to-operate manner, providing a simple and efficient method for constructing complicated bicyclic pyrroles. Additionally, we have successfully synthesized 28 target compounds, which further demonstrates its practicality and wide applicability.
