| Abstract | A robust Ag(I)-catalyzed tandem heterocyclization/[3 + 2] cycloaddition of alpha-alkynylenones with beta-enaminones was developed, enabling efficient synthesis of cyclopenta[c]furans with good yields, operational simplicity, and broad substrate scope. In addition, it also presents an extended methodology to synthesize unsymmetrical tri(hetero)aryl methane having chromone and furan/pyrrole scaffolds by a slight modification of starting materials. Moreover, the synthesized cyclopenta[c]furans exhibit good fluorescence properties with quantum yields ranging from 0.33 to 0.53, as suggested by the photophysical studies. |
