3-Alkyl-substituted 2,4-pyrrolidinediones were directly oxidized under very mild manganese(III)-catalyzed aerobic oxidation conditions to give the corresponding 3-hydroperoxy-2,4-pyrrolidinediones in quantitative yields. The scope and limitations for the synthesis of the hydroperoxyprrolidinediones are described.
Spontaneous Conversion of 3-Alkyl-substituted 3-Hydroperoxypyrrolidine-2,4-diones into 5-Alkyl-5-hydroxyoxazolidin-4-ones
3-Hydroperoxypyrrolidine-2,4-diones substituted with an alkyl group at the 3-position were spontaneously transformed into 5-hydroxyoxazolidin-4-one derivatives at room temperature in air accompanied by the evolution of carbon monoxide.
