Abstract

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 to formal extrusion of one of the peroxide oxygens and produced 1-hydroxy-7-aza-2-oxabicyclo[3.3.0]octanes in quantitative chemical yields.

Abstract

A simple azabicyclic peroxide synthesis was achieved by the manganese(III)-mediated oxidative formal [2+2+2] cycloaddition. A mixture of tetramic acid derivatives and alkenes was oxidized with manganese(III) acetate under a dry air stream to give 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-7-ones in good to quantitative chemical yields.
