Abstract
New syntheses of both substituted and unsubstituted benzobarrelenes are described. Treatment of 3,5-cyclohexadiene-cis-1,2-diol with benzaldehyde dimethylacetal in the presence of a catalytic amount of p-toluenesulfonic acid gave 1,2-(benzylidenedioxy)-3,5-cyclohexadiene(2). Addition of benzynes to 2 provided 3 and 4. Treatment of 3 and 4 with excess LDA and potassium tert-butoxide afforded benzobarrelenes 1 and 5 in good yields.
