Diverse approaches to prepare the nine-membered ring precursor of the DEF fragment of hexacyclinic acid are described, culminating in the synthesis of the CDF ringsystem of this natural product. The key steps are a Michael addition/elimination sequence and an original intramolecular Tsuji–Trost reaction of an enol with an allylic alcohol.
