Total syntheses of (+/-)-debromoflustramine B and E and (+/-)-debromoflustramide B were accomplished using a common and versatile intermediate spirocyclic oxindole 14, which was concisely prepared through intramolecular Ullmann coupling and Claisen rearrangement from iodoindole 13 on a multigram scale.
