Provided is a process for preparing bicyclo[2.2.2]octane-1,4-diol starting from cyclohexane-1,4-dione. The diene is reacted with certain trialkylsilyl halides or trimethylsilyl trifluormethanesulfonate in the presence of a non-nucleophilic base to afford a silyl-substituted diene, which is in turn reacted with ethylene and subsequently reduced to provide the title compound.
提供了一种从环己烷-1,4-二酮制备双环[2.2.2]辛烷-1,4-二醇的过程。二烯与某些三烷基硅卤化物或三甲基硅三氟甲磺酸酯在非亲核碱存在下反应,形成取代硅烷的二烯,然后与乙烯反应,随后还原以得到所述化合物。
