Helicene synthesis by Brønsted acid-catalyzed cycloaromatization in HFIP [(CF(3))(2)CHOH]
A facile synthesis of carbo- and heterohelicenes was achieved via tandem cycloaromatization of bisacetal precursors, which were readily prepared through C–C bond formation by Suzuki–Miyaura coupling. This cyclization was efficiently realized by a catalytic amount of trifluoromethanesulfonic acid (Tf...
