In this article, we introduces a new method for the synthesis of substituted indole by reductive recyclization of bis(5-alkyl-2-furyl)(2-nitroaryl)methane. Bis(5-alkyl-2-furyl)(2-nitroaryl)methane undergo reduction to provide indole or aniline. In the process of research, we found that the chemoselecitivity of reduction was controlled by subtle differences in the electronic effects of the substrate
