摘要

Abstract 5 H-Benzo [b] carbazoles were prepared through a tandem reaction between 2- ethynyl-N-triphenylphosphoranylidene anilines and α-diazoketones through ketenimine intermediates in moderate-to-good yields. By using this approach, benzo [b] benzo [5, 6] indolo [3, 2-h] carbazoles, fluoreno [9, 1-ab] carbazoles, and fluoreno [9, 1-ab] fluoreno [1′, 9′: 5, 6, 7] indolo [3, 2-h] carbazoles were constructed in one pot. Moreover, the resulting ...
