Epoxidation of cholesteryl acetate by a nonradical reagent system such as m-chloroperbenzoic acid, Mo (CO)_6-'BuOOH, or Fe (ClO_4)_3-H_2O_2 was highly α-stereoselective. In contrast, a radical reagent system such as Fe (acac)_3-'BuOOH, KO_2-'BuBr, or biacetyl-O_2-hv, showed high β-selectivity. The stereoselectivity in the epoxidation of cholesteryl acetate seems, therefore, to be a useful indication of the mode of reaction. On this basis, epoxidation may occur through a radical process in the tetraphenylporphinatoiron (III) chloride-iodosylbenzene system. Earlier studies with stilbene had failed to clarify the mechanism in this system.
