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