moiety was tethered at the 3′-β-position of D-threo-furanosides. By carefully controlling the reaction conditions, pyrimidine bases can be delivered to the anomeric center to give of β-pyrimidine nucleosides in good yield and with complete stereocontrol.
嘧啶部分被束缚在D-苏-呋喃糖苷的3'-β-位置。通过仔细控制反应条件,可以将嘧啶碱基递送至异头异构中心,以高收率和完全的立体控制得到β-嘧啶核苷。
