For use in automated synthesis of oligodeoxyribonucleotides, a dimer containing the triesterified internucleotide linkage and the 3 '-phosphoramidite has been prepared. 5 '-O-Dimethoxytritylthymidylyl- (3 '-5') - (o-chlorophenyl) -thymidine was converted to the 3 '- (methyl)N , N-diisopropylphosphoramidite, which has been used as a condensing unit for the synthesis of pentadecathymidylate on controlled pore glass by a deoxyribonucleic acid (DNA) synthesizer.
为了用于寡脱氧核苷酸的自动合成,我们制备了一种含有三酯核苷酸连接和 3'-亚磷酰胺的二聚体。5 '-O-Dimethoxytritylthymidylyl- (3 '-5') - (o-chlorophenyl) -thymidine 被转化为 3 '- (methyl)N , N-二异丙基亚磷酰胺,该亚磷酰胺已被用作缩合单元,通过脱氧核糖核酸(DNA)合成器在可控孔玻璃上合成十β五嘧啶。
