the reagent of choice leading to methylenecyclohexane derivatives in good yields and with complete regioselectivity albeit with poor diastereoselectivity. Using this methodology a stereodivergent synthesis of enantiomerically pure (−)-(2S,6R)-cis-γ-irone and (−)-(2S,6S)-trans-γ-irone, two precious aroma constituents, has been accomplished. This represents an innovative approach with respect to previous
