title: Benzo[b]fluorenes via indanone dianion annulation: a short synthesis of prekinamycin.
abstract: [structure: see text]. A rapid construction of benzo[b]fluorenones via reaction of 1-indanone dianions with phthalate diesters is described. Its utility is illustrated with a concise synthesis of prekinamycin.
