A novel, sequential, palladium-catalyzed, cross-coupling reaction using N-tosylhydrazone and bromonitrobenzene derivatives followed by reductive cyclization has been developed. This transformation providing an efficient route to unexpected N-arylindole derivatives involves, in a one-pot reaction, the formation of one Csp2–Csp2 bond and two Csp2–N bonds together with the cleavage of one Csp2–heteroatom
已经开发出一种新颖的,顺序的,钯催化的,使用N-甲苯磺酰and和溴硝基苯衍生物然后进行还原环化的交叉偶联反应。这种转化提供了通往意外N-芳基吲哚衍生物的有效途径,在一锅反应中涉及一个Csp 2 -Csp 2键和两个Csp 2 -N键的形成以及一个Csp 2-杂原子键的断裂。对生物活性的评估导致鉴定出化合物5a,该化合物在纳摩尔浓度下对人结肠癌细胞系显示出强效活性。
