英文摘要: A novel acid-catalyzed intramolecular Friedel -Crafts alkylation(cyclization) using a spiroketal as electrophile leading to the otherwise not easily accessible benzene-fused 8-oxabicyclo[3.2.1]octane ring system in synthetically useful yields is reported. Slightly more than one equivalent of BF+3.Oet=2 in THF at refluxing temperature are found to be the most satisfactory conditions to achieve the desiredcyclization. An electro-donating group para to the position where cyclization will take placegreatly facilitates the reactiion.
