Diversity-oriented synthesis of novel benzimidazole linked indolo-benzodiazepine/quinoxaline ring systems using poly(ethylene glycol) as soluble polymer support is described. Commercially available 4-fluoro-3-nitrobenzoic acid and indoline were utilized for the construction of these annulated biheterocyclic compound libraries having multiple privileged structures with three-point structural diversity
描述了使用聚(乙二醇)作为可溶性聚合物载体的新型苯并咪唑连接的吲哚-苯并二氮杂/喹喔啉环系统的多样性导向合成。利用市售的4-氟-3-硝基苯甲酸和二氢吲哚来构建这些具有多个特权结构且具有三点结构多样性的环状双杂环化合物库。基于试剂的多样化方法与Pictet-Spengler型缩合反应被用于在取代的苯并咪唑上构建四环吲哚-苯并二氮杂/喹喔啉。
