A variety of 1-indanonyl oxepanes with the novel structure of indanonyl oxepanes was prepared from reaction of hydroxy-benzaldehydes via a series of reasonable transformations, including the regioselective PhBCl2-mediated allylation (or Claisen rearrangement), one-pot reaction of ring-closing metathesis and the Wittig olefination, hydrogenation, and the Friedel-Crafts intramolecular cyclization.
