正在广泛探索 DNA 编码的小分子文库,以在早期药物发现工作中识别结合剂。此类文库的组合合成需要与水和 DNA 相容的反应,而这些反应的缺乏目前限制了所得条形码产品的化学特征。目前的工作在温和的条件下将应变促进的环状丙二烯环加成引入 DNA 编码的文库合成。由于这些反应中间体与活化的烯烃、1,3-偶极子和二烯的不同环加成模式,该过程从单个前体产生了不同的分子结构。由此产生的 DNA 条形码化合物表现出前所未有的环状和地形特征,这些特征与在表型筛选中发现的强大元素相关。

This work describes Ni-catalyzed cross-electrophile coupling of benzyl chloroformate derivatives with aryl iodides that generates a wide range of diaryl methane products. The mild reaction conditions merit the C–O bond radical fragmentation of benzyl chloroformates via halide abstraction or a single electron reduction by a Ni catalyst. This work offers a new substrate type for cross-electrophile couplings
这项工作描述了镍催化的氯甲酸苄酯衍生物与芳基碘化物的交叉亲电子偶联,生成多种二芳基甲烷产物。温和的反应条件使得氯甲酸苄酯的 C-O 键自由基通过卤化物夺取或 Ni 催化剂的单电子还原而断裂。这项工作为交叉亲电子偶联提供了一种新的底物类型。

Several series of carbamate, urea and carboxamide-based CCR5 antagonists have been discovered via optimizations at the amine portion of lead compound 2. All compounds were evaluated for their antiviral activities. Lead urea 29 showed good pharmacokinetic properties, justifying further development of this series. (C) 2010 Elsevier Ltd.
