Visible‐Light‐Driven Synthesis of Pyrrolo[3,4‐ <i>b</i> ]quinolin‐1‐one Imines Exhibiting Aggregation‐Induced Enhanced Emission
In recent years, visible light-mediated transformations have gained significant attention. In this work, we report the synthesis of N-substituted 2,3-dihydro-1H-pyrrolo[3,4-b]quinolin-1-ones via a one-pot strategy involving C(sp<sup>3</sup>)-H functionalization, cyclization, and condensation to form the corresponding imines under visible-light conditions. Furthermore, the imines exhibited Aggregation-Induced Enhanced Emission (AIEE) properties and favorable photophysical response toward metal ions. Subsequent metal-free aerobic oxidation of these imines in the presence of a peroxide medium afforded the corresponding amides. The synthetic utility of this protocol was further demonstrated through post-functionalization of the products and gram-scale synthesis.
