selective solvent extractions, and chemical modification experiments. The feasibility of using imprinted polymers as reusable protecting groups was established by the regioselective acylation of trihydroxysteroids bound to polymers imprinted with structurally related diols. In polymers prepared with tert-butyl ester templates “matched” to the substrate, regioselectivities as high as 23.1:1 (24-acetate:3-acetate)
