Abstract

A new molecularly imprinted Ru–porphyrin complex catalyst on a SiO₂ support was designed, prepared, and characterized in a step-by-step manner for the C₅ [double bond, length as m-dash] C₆ epoxidation of cholesterol derivatives. High chemoselectivity for the C₅C₆ epoxidation of cholesterol derivatives without protecting the 3-position OH group and other oxidizable functional groups was achieved on the molecularly imprinted catalyst.
