Glycosylation of silylated pyrimidines using a phenyl 2-deoxy-3-O-(N-benzoyl)carbamoyl-1-thio-D-erythro-pentofuranoside yielded 2-deoxy-β-ribonucleosides in good yields with excellent anomeric selectivity. This prototype 3-O-carbamate directing group was readily formed and removed in high yields.
使用苯基2-脱氧-3- O-(N-苯甲酰基)氨基甲酰基-1-硫代-D-赤型戊呋喃糖苷对甲硅烷基化的嘧啶进行糖基化反应,可以以良好的收率和优异的异头异构选择性产生2-脱氧-β-核糖核苷。该原型3- O-氨基甲酸酯引导基很容易形成并以高收率除去。
