Chromeno-pyrrole derivatives exhibit a wide range of biological and pharmacological activities. Herein, a novel approach to the synthesis of molecular diversity 2H-chromeno-pyrrole has been developed from [3+2] cyclization of 3-nitrochromenes with cyclic β-enaminones catalyzed by CuI, and DBN as the promoter at room temperature. This reaction has the advantages of good functional group compatibility, broad substrate universality, and mild reaction conditions.

Key words: copper catalyzed, [3+2] cyclization, 2H-chromeno-pyrroles, 3-nitrochromenes, enaminones
