A four-step stereocontrolled synthesis of polyfunctionalized cis-decalins is described, involving oxidation of 2-methoxyphenol, intermolecular Diels−Alder reaction, olefination, and Cope rearrangement. Application of this efficient strategy to the total syntheses of (±)-eremopetasidione, (±)-3β-angeloyloxyfuranoeremophilane, and (±)-3β-methacryloyloxyfuranoeremophilane was accomplished from creosol and ethyl vinyl ketone via a common intermediate 21.
