摘要

Abstract trans-Δ 2-Anhydromevalonic acid (XVII) was prepared by a Wittig reaction, starting from (4-tetrahydro-2-pyranyloxy)-2-butanone. On the other hand, the corresponding 4- acetoxy-2-butanone gave, under similar conditions, the cyclohexene derivative V, explainable by a twofold Michael addition of the Wittig reagent to methyl vinyl ketone, followed by an intramolecular alcol condensation.
