Benzo[b]carbazoles can be synthesised readily and in good yields from the combination of 2,3-unsubstituted indoles and o-phthaldialdehyde in the presence of acid catalysts. Use of phosphoryl chloride in chloroform gives rapid reactions and yields 11-(3-indolyl)benzo[b]carbazoles, whereas the use of p-toluenesulfonic acid in methanol gives slow reactions and yields the isomeric 6-(3-indolyl)benzo[b]carbazoles
在酸催化剂的存在下,由2,3-未取代的吲哚和邻苯二甲醛的组合可以容易地并且以高收率合成苯并[ b ]咔唑。在氯仿中使用磷酰氯可快速反应,生成11-(3-吲哚基)苯并[ b ]咔唑,而在甲醇中使用对甲苯磺酸,则反应缓慢,并生成异构体6-(3-吲哚基)苯并[ b ]咔唑。
