A growing body of evidence supports that pyrimidine derivatives, in which the sugar residues have been replaced by acyclic side chains, might be developed as promising anticancer agents that interfere with tumor cell proliferation, survival, and metastatic formation. In this work, we prepared novel pyrimidines bearing i‐Bu (i.e., 3, 4, and 7–9) and isobutenyl (i.e., 5 and 10) side chains at C(6) and
越来越多的证据支持嘧啶衍生物,其中糖残基已被无环侧链取代,可能被开发为有前途的抗癌剂,干扰肿瘤细胞增殖、存活和转移形成。在这项工作中,我们在 C(6) 处制备了带有 i-Bu(即 3、4 和 7-9)和异丁烯基(即 5 和 10)侧链的新型嘧啶,并检查了它们对肿瘤细胞系的体外作用. 二氢吡咯并[1,2-c]嘧啶-1,3-二酮6和11是分子内环化的产物,发生在5中的Bn或10中的MeO保护基团的去除过程中。用二乙氨基三氟化硫氟化3( DAST),然后将所得氟化衍生物 4 脱卤化氢得到具有 C(2')C(3') 键的 6-异丁-2'-烯基嘧啶衍生物 5。为了制备 6-isobut-1'-en-1-yl pyrimidine 10,应用了一种涉及 1,3-二醇乙酰化的合成策略。化合物 3-11 的抗肿瘤评估表明,含有 6-[(1,3-二苄氧基)-2-羟基] 甲基侧链 3 的 2,4-二甲氧基嘧
