Regioselective Three-Component Reaction of Pyridine N-Oxides, Acyl Chlorides, and Cyclic Ethers [PDF]
Organic Letters, 2017 A novel three-component reaction of pyridine N-oxides, acyl chlorides, and cyclic ethers is described. Treatment of an electron-deficient pyridine N-oxide with an acyl chloride in the presence of a cyclic ether at 25-50 °C leads to a substituted pyridine as a single regioisomer in up to 58% isolated yield.
