Oligonucleotides containing (2′-deoxy-β-D-xylofuranosyl)guanine have been prepared. For this purpose 2-aminoadenosine (5) was synthesized and converted to 2′-deoxy-β-D-xyloguanosine (1). The related 2′-deoxy-β-D-xyloisoguanosine (3) and 2′-deoxy-β-D-xyloxanthosine (4) were also synthesized. Compound 1 was converted to the phosphonate and phosphoramidite building blocks 10 and 11, respectively. The
已经制备了含有(2'-脱氧-β-D-木呋喃糖基)鸟嘌呤的寡核苷酸。为此目的,合成了2-氨基腺苷(5)并将其转化为2'-脱氧-β-D-木葡糖苷(1)。还合成了相关的2'-脱氧-β-D-木基异鸟苷(3)和2'-脱氧-β-D-木基黄嘌呤(4)。化合物1分别转化为膦酸酯和亚磷酰胺结构单元10和11。寡脱氧核苷酸(5'-3')d(xG-xT-xA-xG-xA-xA-xT-xT-xC-xT-xA-xC-T)(18)形成一个双链体,其T m与亲本(5′-3′)-(GTAGAATTCTAC)(19),但CD频谱倒置。
