Cyclohexyl nucleosides with an adenine and uracil base have been synthesized from 2-azidocyclohexane-1,5-diol. The obtained racemic nucleosides were resolved using (R)-O-methylmandelic acid. Short oligonucleotides were synthesized using phorphoramidite chemistry. However, these oligonucleotides do not show self-hybridization, and duplexes are less stable than those of ribopyranosyl-(4′ 2′)-oligonucleotides
具有腺嘌呤和尿嘧啶碱基的环己基核苷已由2-叠氮基环己烷-1,5-二醇合成。使用(R)-O-甲基扁桃酸拆分获得的外消旋核苷。使用磷酰胺酰胺化学合成短的寡核苷酸。然而,这些寡核苷酸不显示自身杂交,并且双链体不如核吡喃糖基-(4'2')-寡核苷酸的双链体稳定。
