| Abstract: | A novel N‐heterocyclic carbene (NHC)‐palladium‐catalyzed three‐component cascade cyclization/alkynylation for the synthesis of structurally diverse 4‐alkynylisoxazoles was efficiently developed in ionic liquids. The operational simplicity, without additives, no additional ligands, and 0.5 mol % catalyst loading under air are some of the attractive features of this present protocol. |
