Original substitutedpyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5-amines have been prepared following a Groebke–Blackburn–Bienaymé MCR combined with an N-deprotection and a spontaneous final cyclization step in moderate to good yields. The flexibility of the described method enables the introduction of diverse groups in the 6 and 7 positions on the resulting scaffold using commercially available starting
在Groebke–Blackburn–Bienaymé MCR结合N-脱保护和自发的最终环化步骤后,制备了原始的取代吡啶并[2',1':2,3]咪唑并[4,5- c ]异喹啉-5-胺中等至良好的产量。所描述的方法的灵活性使得能够使用可商购的起始材料在所得支架上的6和7位引入不同的基团。此外,使用我们的杂环伯胺衍生物已成功报道了布赫瓦尔德-哈特维格与各种芳基和杂芳基卤化物的交叉偶联。

synthetic protocol has been devised to access cationic gold(III) bis(2-pyridylimino)isoindolato (BPI) complexes. The rigid BPI framework was shown to stabilize this type of coordination compound and allowed different substitution patterns in the ligand periphery. The synthesis of these complexes tolerates both air and moisture and does not require transmetalation steps with toxic thallium or mercury compounds
