An efficient method for the synthesis of new polycyclic skeletons: pyrido[2′,1′:2,3]imidazo[5,4-c]quinolin-6(5H)-ones and pyrido[2′,1′:2,3]imidazo[5,4-c]azepin-7(6H)-ones libraries is described via Pd-catalyzed intramolecular arylation involving C(sp2)-H activation. This method permits the synthesis of polycyclic derivatives in good yield. The process tolerates a variety of aryl substituents as well
一种合成新的多环骨架的有效方法:吡啶并[2',1':2,3]咪唑并[5,4 - c ]喹啉-6(5 H)-ones和吡啶并[2',1':2 ,3]咪唑并[5,4 - c ] azepin-7(6 H)-ones文库是通过Pd催化的涉及C(sp2)-H活化的分子内芳基化进行描述的。该方法允许以高收率合成多环衍生物。该方法耐受各种芳基取代基以及烷基咪唑并[1,2 - a ]吡啶-2-羧酰胺结构。在Suzuki交叉偶联条件下将所得化合物10(11)-氯-吡啶并[2',1':2,3]咪唑并[5,4- c ]喹啉酮或氮杂环庚烷酮官能化以得到多官能化合物。
