RESUMO
A visible-light-induced cascade reaction is described for the one-pot synthesis of 6-hydroxyindoloquinazolinones using isatins (or isatins and isatoic anhydrides) and aliphatic carboxylic acids. The method provides 36 desired products in 33-96% yield, exhibiting broad substrate scope and good functional group tolerance. This approach utilizes inexpensive and commercially available starting materials, enabling the direct construction of high-value complex structures under mild conditions without the need for photocatalyst, showcasing significant applicability and environmental friendliness.
