The universal solid support, USIII, representing a new and improved version of commercial USII, as well as 2 ′-deoxynucleoside and 2 ′-deoxy-2 ′-fluoronucleoside bound supports, incorporating a labile phenoxyacetyl fragment, was synthesized by an aminomethyl polystyrene carbamoylation with corresponding azides in the presence of aqueous triethylammonium bicarbonate. All three solid phases incorporate
通过氨基甲基聚苯乙烯氨基甲酸酯化反应合成了通用的固体支持物USIII,它代表了商业USII的新的改进版本,以及2'-脱氧核苷和2'-脱氧-2'-氟核苷结合的支持物,并结合了不稳定的苯氧乙酰基片段。在碳酸氢三乙铵水溶液中与相应的叠氮化物反应。所有三个固相均包含稳定的尿素系链,从而桥接了聚合物和功能性连接基。这些新基质被证明是强大的固相,可用于合成DNA,RNA或修饰的寡核苷酸以及随机混合的2'-ribo / 2'-deoxy-2'-fluoro-RNA库和/或DNA库,三核苷酸(密码子)。
