A very simple and efficient method is described for the protection of alcohols and nucleosides with benzyl monomethoxytrityl and benzyl dimethoxytrityl ethers in the presence of diethylazodicarboxylate and a catalytic amount of ceric triflate. High selectivity was observed for the tritylation of 5′-OH function of nucleosides.
