preparation of synthetic 2′-deoxynucleosides, which have various biological and biotechnological applications. In this work, the Mitsunobu-based synthesis of 2′-deoxynucleosides was systematically studied. The effect of phosphine, azodicarbonyl reagent, and solvent on the product yield and α/β ratio was investigated, and the highest yield and β-selectivity were obtained using ( n -Bu) 3 P and 1,1′-(azodic
Mitsunobu 反应已成为制备具有各种生物学和生物技术应用的合成 2'-脱氧核苷的重要替代方法。在这项工作中,系统研究了基于光信的 2'-脱氧核苷合成。考察了膦、偶氮二羰基试剂和溶剂对产物收率和α/β比的影响,使用( n -Bu) 3 P和1,1'-(偶氮二羰基)二哌啶获得了最高的收率和β-选择性在 DMF 中。该反应成功地应用于各种核碱基类似物。
