Novel unsaturated acyclic nucleoside analogues, 1-1-[1-(hydroxymethyl)prop-2-enyloxy]prop-2-enyl}uracil, 1-1-[1-(hydroxymethyl)prop-2-enyloxy]prop-2-enyl}thymine and 1-1-[1-(hydroxymethyl)prop-2-enyloxy]prop-2-enyl}cytosine have been prepared in good yield from uridine and 5-methyluridine by periodate cleavage followed by a double Wittig reaction which introduces two vinyl groups. The thymine derivative
新型不饱和无环核苷类似物,1- 1- [1-(羟甲基)丙-2-烯氧基]丙-2-烯基}尿嘧啶,1- 1- [1- [1-(羟甲基)丙-2-烯氧基]丙-通过尿酸和5-甲基尿苷的高碘酸盐裂解,再加两次Wittig,从尿苷和5-甲基尿苷中以高收率制备了2-烯基胸腺嘧啶和1- 1- [1-(羟甲基)丙-2-烯氧基]丙-2-烯基}胞嘧啶引入两个乙烯基的反应。胸腺嘧啶衍生物进行了闭环复分解反应,以合成d4T。
