of a number of DNA polymerases, including the reverse transcriptases of human immunodeficiency virus type 1 (HIV-1) and avian myeloblastosis virus (AMV). None of the DNA polymerases examined were able to incorporate this compound into the growing DNA chain. In contrast, 3'-C-methylidene-2',3'-dideoxy-5-methyluridine 5'-triphosphate was found to be incorporated at the 3'-end of the DNA chain by HIV-1
已经提出了以2-脱氧核糖为原料的3'-C-甲基-2'-脱氧核苷和3'-C-亚甲基-2',3'-二脱氧-5-甲基尿苷的合成方案。将5-O-苯甲酰基-2-脱氧核糖呋喃糖甲基氧化,并将3'-酮衍生物的混合物分离为α-和β-端基异构体。通过与MeMgBr反应,与胸腺嘧啶反应并随后脱保护1-(3'-C-甲基-2'-α-脱氧-α-D-苏-五氟呋喃糖基)胸腺嘧啶及其β-获得了异头物。与α-酮糖的相同反应得到1-(3'-C-甲基-2'-脱氧-α-D-赤型五呋喃糖基)胸腺嘧啶及其β-异头物。将1-(5-O-苯甲酰基-3'-C-甲基-2'-脱氧-α-D-苏-五氟呋喃糖基)胸腺嘧啶转化为3'-C-亚甲基-2',3'的混合物 分离了-二脱氧-5-甲基尿苷和3'-C-甲基-2',3'-二脱氧-2',3'-二氢-5-甲基尿苷。格氏试剂与2-脱氧呋喃糖3-核苷的连接的立体选择性由Cl处的取代构型决定。此外,还研究了C3
