[2'-deoxy-1'-C,4'-C-(2-oxapropano)uridine] (15), expected to be restricted into an O4'-endo furanose conformation, was synthesized from the known 1-(3'-deoxy-beta-D-psicofuranosyl)uracil 5. The phosphoramidite derivative of 15 was successfully incorporated into oligodeoxynucleotides using standard methods, and thermal denaturation studies showed moderate decreases in duplex stabilities of -2.1 and -1
新型双环核苷(1S,5S,6S)-6-羟基-5-羟甲基-1-(尿嘧啶-1-基)-3,8-二氧杂双环[3.2.1]辛烷[2'-脱氧-1'-由已知的1-(3'-脱氧-β-D-psico呋喃糖基)合成预期被限制为O4'-内呋喃糖构象的C,4'-C-(2-氧杂丙烷)尿苷](15)尿嘧啶5。使用标准方法成功地将15的亚磷酰胺衍生物掺入到寡脱氧核苷酸中,热变性研究表明,针对互补DNA和RNA的每种修饰,双链体稳定性分别适度降低-2.1和-1.5℃。
