Abstract
AbstractAcid mediated cyclopropylcarbinol ring expansion has been shown to be a viable method for the construction of the AB ring framework of lancifodilactone F and related terpenoids of the Schisandraceae family of natural products. We found that this rearrangement proceeds with good stereochemical control based on inversion of the C10 cyclopropyl center. Our studies indicate that the cis‐decalin motif of 31 could be used as a key synthetic precursor of certain Schisandraceae metabolites.(© Wiley‐VCH Verlag GmbH & Co.
