Protected adenosine 3 was oxidized using Moffatt reagent to give the 3′-ketoadenosine 4 in 60% yield. Stereospecific reduction of 4 with sodium borohydride in the presence of triethylamine at - 18°C followed by deprotection effects the inversion of configuration at C-4 affording 9-β-D-(xylofuranosyl)adenine (7).
保护的腺苷3使用Moffatt试剂氧化,得到3′-酮腺苷4,产率为60%。在-18°C下,四乙胺存在的情况下,使用氢化钠对4进行立体选择性还原,随后去保护效果导致C-4的构型反转,得到9-β-D-(木糖呋喃糖基)腺苷(7)。
