A new and efficient two‐step procedure for the preparation of 5,7‐disubstituted 5,7‐dihydropyrido[2,3‐b:6,5‐b′]diindoles, containing aryl‐, benzyl‐ as well as alkyl‐substituents has been developed. This methodology consists of a chemo‐selective double Suzuki‐Miyaura cross‐coupling reaction followed by a fourfold Buchwald‐Hartwig amination reaction. UV/VIS absorption and fluorescence measurements have
一种新的高效两步法,可制备包含芳基,苄基和烷基取代基的5,7-二取代的5,7-
二氢吡啶并[2,3- b:6,5- b ']二
吲哚已经被开发出来。该方法包括一个
化学选择性的Suzuki-Miyaura双交叉偶联反应,然后是四倍的Buchwald-Hartwig胺化反应。已对选定的一系列化合物进行了UV / VIS吸收和荧光测量。对结果进行了总结,并与同分异构的5,7-二取代的5-7-
二氢吡啶并[3,2- b:5,6 - b ']二
吲哚进行了比较。
