Enantioselective installation of adjacent tertiary benzylic stereocentres using lithiation–borylation–protodeboronation methodology. Application to the synthesis of bifluranol and fluorohexestrol
and synthesis of 4-substituted 7-(3-fluoro-4-methoxybenzyl)-7H-pyrrolo[2,3-d]pyrimidines of scaffold 6 as anticancer agents. A total of 19 derivatives of scaffold 6 bearing a C-4 alkoxy, dialkylamino, alkyl, vinyl, or phenyl substituent were synthesized and evaluated. Among them, compound 6q having a C-4 ethyl group and a benzylic methyl group showed the most potent in vitro anticancer activity, inhibiting
在本文中,我们报告了支架6的 4-取代 7-(3-氟-4-甲氧基苄基)-7 H-吡咯并[2,3- d ]嘧啶作为抗癌剂的设计和合成。合成并评估了带有 C-4 烷氧基、二烷基氨基、烷基、乙烯基或苯基取代基的支架6 的总共 19 种衍生物。其中,具有 C-4 乙基和苄基甲基的化合物6q显示出最有效的体外抗癌活性,在亚微摩尔浓度下抑制 Hela、MDA-MB-231 和 MDA-MB-426 癌细胞的增殖。 GI 50:0.11–0.58 μM)。化合物6q在 G 2处阻止 MDA-MB-231 的细胞周期/M 期,并对携带 MDA-MB-231 异种移植物的裸鼠显示体内活性。化合物6q已用作进一步优化的抗癌先导物。
