Abstract: A practical, organophosphoric acid-catalyzed, two-component cyclization–aromatization reaction of 3-vinylindoles with 2-vinylpyridines has been established for the efficient assembly of various functionalized 1-pyridin-2-yl-9 H -carbazole skeletons. This transformation involves an organophosphoric acid-catalyzed [4+2] cycloaddition reaction, together… read more here.
