Convenient Synthesis of Quinoline-4-carboxylate Derivatives through the Bi(OTf)<sub>3</sub>
-Catalyzed Domino Cyclization/Esterification Reaction of Isatins with Enaminones in Alcohols
An efficient protocol for the synthesis of quinoline‐4‐carboxylates through a Bi(OTf)3‐catalyzed domino cyclization/esterification reaction of isatins with enaminones is described.
