4-甲氧基三苯代甲基醇 | p-methoxytrityl alcohol | 847-83-6 | C20H18O2 | 290.362 |
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.
