A simplified and economical method for the attachment of 2'-deoxyribo, ribo and arabinonucleosides onto long-chain alkylamidopropanoic acid controlled-pore glass (LCAAP-CPG, P-3) is described. In this procedure, 5'-O-tritylated nucleosides are coupled directly to LCAAP-CPG in excellent yields using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (DEC) as coupling reagent. The conventional and time-consuming preparation of nucleoside-3'-O-succinates is no longer required.
描述了一种将2'-脱氧核糖核苷、核糖核苷和阿拉伯核苷连接到长链烷基酰胺基丙酸可控孔玻璃(LCAAP-CPG,P-3)上的简化且经济的方法。在此方法中,使用1-(3-二甲基氨基丙基)-3-乙基碳二亚胺(DEC)作为偶联试剂,5'-O-三苯甲基化核苷以优异的产率直接与LCAAP-CPG偶联。不再需要常规且耗时的核苷-3'-O-琥珀酸酯的制备。
