Derivatization of a hydroxyl group into the tert-butyldimethylsilyl ether was shown to be useful for selective blockage of coordination of the substrate with the lanthanide shift reagent in 1H nuclear magnetic resonance spectroscopy. This method was conveniently applied to confirmation of the labeled position with deuterium in the dioxygenated steroids.
