Facile Access to 3-Alkyl-Substituted 3-Hydroperoxy-2,4-pyrrolidinediones Using Manganese(III)-Catalyzed Aerobic Oxidation
摘要:
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.

Twenty‐two 3‐alkyl‐4‐hydroxy‐1H‐pyrrol‐2(5H)‐ones were prepared and underwent Mn(III)‐catalyzed aerobicoxidation in the presence of 1,1‐diarylethenes to produce very stable crystalline 6‐alkyl‐8‐aza‐4,4‐diaryl‐1‐hydroxy‐2,3‐dioxabicyclo[4.3.0]nonan‐7‐ones in high yields.
