(±)-3-Amino-1-(4,4′-dimethoxytriphenylmethyl)-2-propanediol was attached to succinylated alkylamino-controlled pore glass via the second amide bond. The resulting solid phase was acylated to give seven new universal solid supports, compatible with the preparation of all common types of oligodeoxyribonucleotides. These resins allow for fast elimination of the 3′-terminal phosphodiester or phosphorothioate
通过第二酰胺键将(±)-3-氨基-1-(4,4'-二甲氧基三苯基甲基)-2-丙二醇连接到琥珀酰化的烷基氨基控制的孔玻璃上。将所得固相酰化,得到七个新的通用固相支持物,与所有常见类型的寡脱氧核糖核苷酸的制备相容。这些树脂允许在室温下通过甲醇中的氨快速消除3'-末端磷酸二酯或硫代磷酸酯的功能。
