  摘要：

  通过相应硝基化合物的脱氧作用或相关叠氮化物的热解或光解反应制得的2-（2-硝基苯基）苯并噻唑通过攻击苯并噻唑氮而得到吲唑并[3,2- b ]苯并噻唑。在（2-（2-硝基苯基）苯并咪唑中，类似的氮原子侵蚀使得苯并咪唑并吲唑具有良好的收率。但是，在苯并咪唑中有适当的1-取代基（例如Me或CHMe 2）时，三重态（通过苯乙酮敏化的光解作用或带有4-二甲氨基的叠氮化物的热分解产生）的腈优先攻击该取代基得到苯并咪唑并喹唑啉。

  serotonin and serotonin3 (5-HT3) antagonists using a two-dimensional grid template composed of regular hexagons, we deduced structural modification patterns from agonists to antagonists, and designed new 5-HT3 antagonist prototypes. Among them, 2-(4-methyl-1-piperazinyl)-1-butylbenzimidazole (6) was identified as a lead compound which has potent 5-HT3 antagonistic activity comparable to that of granisetron

  通过使用由规则六边形组成的二维网格模板对5-羟色胺和5-羟色胺（5-HT3）拮抗剂进行结构比较研究，我们推导了从激动剂到拮抗剂的结构修饰方式，并设计了新的5-HT3拮抗剂原型。其中，将2-（4-甲基-1-哌嗪基）-1-丁基苯并咪唑（6）鉴定为具有与格拉司琼相当的强5-HT3拮抗活性的先导化合物。我们使用定量构效关系方法优化了6的结构并选择了6-氨基-5-氯-1-异丙基-2-（4-甲基-1-哌嗪基）苯并咪唑二马来酸酯（69，KB-6933），最有效和长效的5-HT3拮抗剂之一，作为候选药物。

Otherwise, 2-amino-1H-benzimidazoles and strongly fluorescent 3-amino-2H-indazoles, originating from rearrangements of the elusive 1-aryl-3-iminodiaziridines, predominate. N′,N″-Diaryl-N-hydroxyguanidine O-sulfonic acids give only rearranged products: a 2-amino-1H-benzimidazole and a 6-amino-5H-dibenzo[d,f][1.3]diazepine if aryl = phenyl, or a 2-imino-2,3-dihydro-3aH-benzimidazole
