1,2-Oxaselenolane Se-oxide is a novel cyclic seleninate ester that functions as a remarkably efficient glutathione peroxidase mimetic by catalyzing the reduction of tert-butyl hydroperoxide to tert-butyl alcohol in the presence of benzyl thiol. The seleninate ester can be conveniently generated in situ by oxidation of allyl 3-hydroxypropyl selenide with tert-butyl hydroperoxide. Its catalytic activity surpasses that of several other known GPx mimetics containing cyclic selenenamide structures, which were also tested for comparison.
