A Simple and Effective Synthesis of Benzolactones and Benzolactams by Noncatalytic Benzylic Oxidation of Cyclic Benzylic Ethers and N-Protected Cyclic Benzylic Amines with Sodium Chlorite as an Oxidant
摘要:
Sodium chlorite (NaClO2) was shown to be capable of oxidizing cyclic benzylic ethers and N-protected cyclic benzylic amines in a heterogeneous solvent system of 1,1,1-trichloroethane and water at 55-65 degrees C to give synthetically useful benzolactones and benzolactams, respectively, in high-to-excellent yields.
