A visible-light photoredox catalyzed ring-opening functionalization of tetrahydroisoquinolines with bisindole alkylation has been developed, which expedites a new vista for the synthesis of bis(indolyl)methane derivatives. The transformation comprises a series of cascade reactions, photoredox catalysis, amine oxidation, fragmentation and Friedel–Craft alkylation. Five of the prepared bis(indolyl)methane derivatives containing the para substitution group on the side chain of benzene suppressed cancer cell growth in human breast adenocarcinoma MDA-MB-231 cells, and one candidate demonstrated a significant effect on cell migration.
