The synthesis of several 1,2-diaryl-1H-4,5,6,7-tetrahydro-1,3-diazepines 1 by cyclization of N-aryl-N'-benzoyltetramethylenediamines 2 is described. Two alternative synthetic routes to obtain precursors 2 are discussed, being that which employes pyrrolidine as starting material the most convenient. Nucleophilic attack of compounds 1 on methyl iodide affords 1,2-diaryl-1H-4,5,6,7-tetrahydro-1,3-diazepinium
的几个1,2-二芳基-1-合成ħ -4,5,6,7-四氢-1,3-二氮杂1通过环化ñ -芳基- N'- benzoyltetramethylenediamines 2进行说明。讨论了获得前体2的两种替代合成途径,最方便的是采用吡咯烷作为起始原料。化合物1对甲基碘的亲核攻击得到1,2-二芳基-1 H -4,5,6,7-四氢-1,3-二氮杂吡啶鎓碘化物3。1这些化合物的H-NMR谱明确地通过NOESY实验来分配,1个化合物的H-NMR谱1分析和比较化合物3和3和它们本身以及与在三氟乙酸-d存在下运行的化合物1的化合物。用硼烷还原化合物1在区域上导致N-芳烷基-N'-芳基四亚甲基二胺7。
