Three protected derivatives of 1,N6-ethenoadenine nucleosides, viz. 3-[5-O-(4,4 ′-dimethoxytrityl) of 7-formyl-(1) and 7-(1,2-diacetyloxypropyl)-2 ′-deoxyadenosine (2), and 3-[5-O-(4,4 ′-dimethoxytrityl)-2-O-(tert-butyldimethylsilyl)-7-(ethoxycarbonyl)adenosine (3), expected to allow introduction of formyletheno and carboxyethenoadenine adducts into oligonucleotides by the conventional phosphoramidite
1,N6-乙烯腺嘌呤核苷的三种受保护衍生物,即。7-甲酰基-(1)和7-(1,2-二乙酰氧基丙基)-2'-脱氧腺苷(2)的3-[5-O-(4,4'-二甲氧基三苯甲基)和3-[5-O- (4,4'-二甲氧基三苯甲基)-2-O-(叔丁基二甲基甲硅烷基)-7-(乙氧基羰基)腺苷 (3) 预计允许通过常规亚磷酰胺化学将甲酰乙烯和羧基乙烯腺嘌呤加合物引入寡核苷酸中。
