Palladium-catalyzed hydrogenolysis of azabicyclic peroxides. Quantitative transformation to 1-hydroxy-7-aza-2-oxabicyclo[3.3.0]octanes

The palladium-catalyzed reduction of 1-hydroxy-8-aza-2,3- dioxabicyclo[4.3.0]nonanes, which were readily obtained by the manganese(III)-mediated oxidative formal [2+2+2] cycloaddition of pyrrolidinedione derivatives with alkenes and molecular oxygen, led

Mn(III)-based reaction of alkenes with pyrrolidinedione derivatives. Formation of bicyclic peroxides and the related compounds

Alkenes (1) and 2,3-pyrrolidinediones (2) were treated with manganese(III) acetate in acetic acid at 23°C under a stream of dry air giving 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-9-ones (3) in good yields. The reaction at elevated temperature gave 4-ethenyl-2,3-pyrrolidinediones (6) and/or 4-alkyl-2,3-pyrrolidinediones (7) in good yields. A wide variety of 2,3-pyrrolidinediones having an alkoxycarbonyl, cyano, or acyl group at the 4-position were tested to delineate the scope and limitations of these reactions. The mechanisms for the formation of the products were also discussed.

Mn(III)-Induced molecular oxygen trapping reaction of alkenes with 2,3-pyrrolidinedione derivatives. A novel entry to 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-9-ones

Molecular oxygen trapping reaction of alkenes with 2,3-pyrrolidinedione derivatives was developed using a Mn(III)-induced oxidation system. Alkenes and 2,3-pyrrolidinediones were treated with manganese(III) acetate in acetic acid under a stream of dry air, giving 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-9-ones in good yields, The reaction involved molecular oxygen trapping of radicals which were formed by the addition of pyrrolidinedione radicals induced by Mn(III) to alkenes.
