  • Enantioselective Synthesis of 3-Arylquinazolin-4(3<i>H</i>)-ones via Peptide-Catalyzed Atroposelective Bromination
    作者:Matthew E. Diener、Anthony J. Metrano、Shuhei Kusano、Scott J. Miller

    atroposelective bromination of pharmaceutically relevant 3-arylquinazolin-4(3H)-ones (quinazolinones) with high levels of enantioinduction over a broad substrate scope. The structure of the free catalyst and the peptide-substrate complex were explored using X-ray crystallography and 2D-NOESY experiments. Quinazolinone rotational barriers about the chiral anilide axis were also studied using density functional
    我们报告了一种含叔胺的 β-转角肽的开发,该肽可催化药物相关的 3-芳基喹唑啉-4(3H)-酮(喹唑啉酮)的间质选择性溴化,在广泛的底物范围内具有高水平的对映诱导作用。使用 X 射线晶体学和 2D-​​NOESY 实验探索了游离催化剂和肽-底物复合物的结构。还使用密度泛函理论计算研究了围绕手性苯胺轴的喹唑啉酮旋转势垒,并根据观察到的高对映选择性进行了讨论。机理研究还表明,最初的溴化事件是立体决定的,主要的一溴化物中间体是一种阻转异构稳定的单邻位取代异构体。立体异构稳定的一溴化物的观察刺激了三溴化物产物转化为其他阻转异构定义的感兴趣的产物。例如,(1) 脱卤 Suzuki-Miyaura 交叉偶联序列提供邻位芳基化衍生物,(2) 区域选择性 Buchwald-Hartwig 胺化程序安装对胺官能团。在这些后续转化过程中保留了立体化学信息。
  • Atroposelective Desymmetrization of Resorcinol-Bearing Quinazolinones via Cu-Catalyzed C–O Bond Formation

    atropisomeric resorcinol-bearing quinazolinones have been developed. Utilizing a new guanidinylated dimeric peptidic ligand, a set of products were generated in good yields with excellent stereocontrol. The transformation was readily scalable, and a range of product derivatizations were performed.

  • Synthesis, Structure−Activity Relationships, and Biological Profiles of a Quinazolinone Class of Histamine H<sub>3</sub> Receptor Inverse Agonists

    日期:2008.8.1
    A new series of quinazolinone derivatives was synthesized and evaluated as nonimidazole H(3) receptor inverse agonists. 2-Methyl-3-(4-[3-(1-pyrrolidinyl)propy]oxy}phenyl)-5-(trifluoromethyl)-4(3H)-quinazolinone (1) was identified as a promising derivative for further evaluation following optimization of key parameters. Compound 1 has potent H3 inverse agonist activity and excellent selectivity over other histamine receptor subtypes and a panel of 115 unrelated diverse binding sites. Compound 1 also shows satisfactory pharmacokinetic profiles and brain penetrability in laboratory animals. Two hours after oral administration of 30 mg/kg of 1 to SD rats, significant elevation of brain histamine levels was observed where the brain H3 receptor was highly occupied (>90%). On the basis of species differences in P-glycoprotein (P-gp) susceptibility of I between human and rodent P-gps, the observed rodent brain permeability of I is significantly limited by P-gp mediated efflux in rodents, whereas the extent of P-gp mediated efflux in humans should be very small or negligible. The potential of 1 to be an efficacious drug was demonstrated by its excellent brain penetrability and receptor occupancy in P-gp-deficient CF-1 mice.

  • Pd‐Catalyzed Carbonylative Synthesis of 4 <i>H</i> ‐Benzo[ <i>d</i> ][1,3]Oxazin‐4‐Ones Using Benzene‐1,3,5‐Triyl Triformate as the CO Source

    A Pd-catalyzed CO-free carbonylative synthesis of 4H-benzo[d][1,3]oxazin-4-one derivatives was developed. This new method employed readily available N-(o-bromoaryl)amides as the starting materials and inexpensive benzene-1,3,5-triyl triformate (TFBen) as the stable solid CO surrogate, which would not cause hydrodehalogenation of the starting materials. Remarkably, this method featured a very broad
