Abstract

The carbazole alkaloids have profound biological activities and material properties. We reported that 3, 4-substituted, 3-substituted and 4-substituted carbazoles were regioselectively synthesized from indoline derivatives by means of Diels-Alder reaction in the presence or absence of Pd catalyst and attained the synthesis of natural carbazole alkaloid from 3-substituted carbazole, too.
