The t-butyldimethylsilyl group is shown to be an ideal protecting group for the 2T-hydroxyl function of ribonucleosides during the synthesis of ribonucleotides using any of nine commonly used condensing agents. The phosphite coupling procedure compares favorably with all of the widely used condensing agents and provides a most convenient route to the key intermediates in the "modified" triester strategy.
在使用九种常用缩合剂中的任何一种合成核糖核苷酸的过程中,叔丁基二甲基硅烷基被证明是核糖核苷2'-羟基功能的理想保护基团。亚磷酸酯偶联方法与所有广泛使用的缩合剂相比具有优势,并为“改良”三酯策略中的关键中间体提供了一条非常便捷的途径。
