H-Phosphonate synthesis of oligodeoxynucleotids is described in which acetonitrile is replaced by dichloromethane. This solvent is thereafter easily regenerated and reused. Practically "one solvent" procedure of oligonucleotide synthesis has been established. The preparation of 5'-O-(4,4'-dimethoxytriphenylmethyl)-N2-(N,N-dimethylaminomethylene)-2'-deoxyguanosine (Ic) and 5'-O-(4,4'-dimethoxytriphenylmethyl)-N6-(N,N-dimethylaminomethylene)-2'-deoxyadenosine (Id) is described.
本文介绍了一种使用
二氯甲烷替代
乙腈的H-
磷酸酯合成寡聚脱氧核苷酸的方法。该溶剂可以被轻松再生和重复使用,从而建立了一种“单溶剂”合成寡核苷酸的实用程序。同时,文中还介绍了5'-
