Synthesis of Functionalized Chromeno[2,3‑b]pyrrol-4(1H)‑ones by Silver-Catalyzed Cascade Reactions of Chromones/Thiochromones and Isocyanoacetates
A novel and convenient approach to the synthesis of chromeno[2,3-b]pyrrol-4(1H)-ones has been developed. Furthermore, the method involves a facile silver-catalyzed cascade cyclization reaction including an intramolecular C–O bond formation. The silver salt acts as a key promoter.
