route to (±)-β-cuparenone () are reported. Thus, orthoester Claisenrearrangement of the cinnamyl alcohol furnished the eneester . Anhydrous CuSO, catalysed intramolecular cyclopropanation of the diazoketone derived from the ene-acid , generated a diastereoisomeric mixture of cyclopropylketone . The Huang-Minlon reduction of the ketones and furnished the cyclolaurene () and epicyclolaurene (), whereas
