The synthesis of 2′-C-hydroxymethyl and 2′-C-methyl nucleoside analogs [1-(3-deoxy-2-hydroxymethyl-D-erythro-pentofuranosyl)-thymine (14), the corresponding adenine derivative. 17, 1-(2-methyl-β-D-ribofuranosyl)thymine (20) and 2′-methyladenosine (23)] by coupling of sugar moieties, easily prepared from α-D-isosaccharino-and α-D-glucosaccharino-1,4-lactone derivatives, respectively, with silylated thymine or 6-chloropurine is reported.
报道了通过将糖基的耦合合成2′-C-羟甲基和2′-C-甲基核苷类似物[1-(3-脱氧-2-羟甲基-D-赤藓糖基)-胸腺嘧啶(14),对应的腺嘌呤衍生物17,1-(2-甲基-β-D-核糖基)胸腺嘧啶(20)和2′-甲基腺苷(23)],这些糖基分别由α-D-异糖和α-D-葡萄糖-1,4-内酯衍生物轻松制备,并与硅化胸腺嘧啶或6-氯嘌呤耦合而成。
