An efficient method for the synthesis of N‐alkylated 3‐(1‐benzyl‐1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazoles (5, 6, 7, 8, 9, 10) and 9‐ethyl‐3,6‐di(1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazole (13) has been developed from nitroolefines. The effects of catalyst and solvent on these reactions have been investigated. p‐TsOH‐THF was found to be the best system for this reaction. Various triazolyl‐carbazoles were prepared
用于合成的有效方法Ñ烷基化3-(1-苄基1 ħ 1,2,3-三唑-4-基)-9- ħ -carbazoles(5,6,7,8,9,10)和9-乙基-3,6-二(1 H -1,2,3-三唑-4-基)-9 H-咔唑(13)由硝基烯烃开发而成。已经研究了催化剂和溶剂对这些反应的影响。已发现对-TsOH-THF是该反应的最佳体系。制备了各种三唑基咔唑,收率良好至优异。
