Title
Pentanidium catalyzed enantioselective hydroperoxidation of 2-oxindole using molecular oxygen
Abstract

•Parameters affecting the yield and ee of hydroperoxide were studied.•Mechanistic study was conducted to elucidate the pathway.•Hydroperoxide was obtained by direct insertion of dioxygen into 2-oxindole.•Byproduct was generated by preferential reduction of R-hydroperoxide.

Pentanidium catalyzed enantioselective 3-hydroperoxidation of 2-oxindoles with molecular oxygen has been established. Various 3-hydroperoxy-2-oxindoles were achieved in good ee and yield.
