The singlet oxygenation of 6-substituted 1,4-cyclooctadienes gave cis-5,8- and trans-5,6-difunctionalized 1,3-cyclooctadienes stereoselectively. According to the mol. structures of the products, the conformation of 6-substituted 1,4-cyclooctadienes was twisted in this ene reaction. Electron-donating substituents enhance the ene reaction, while electron-withdrawing substituents have the opposite effect.
