Oxidation of vic-Diols to .alpha.-Dicarbonyl Compounds Using the Oxoammonium Salt Derived from 4-Acetamido-TEMPO and p-Toluenesulfonic Acid
摘要:
Both open-chain and cyclic vicinal-diols are oxidized to the corresponding alpha-dicarbonyl compound by the oxoammonium salt derived from 4-acetamido-TEMPO and p-toluenesulfonic acid. With certain exceptions, yields are as high or higher than those obtained when Swern reagents are used to effect the same conversions.
