Soluble cycloannulated tetroxa[8]circulane derivatives: Synthesis, optical and electrochemical properties, and generation of their robust cation-radical salts

Syntheses of soluble bicycloalkane-annulated tetraoxa[8]circulane derivatives via Lewis acid-catalyzed tetramerization of readily available cycloannulated benzoquinons is described. The ready availability of the soluble circulane derivatives allows the evaluation of their optical and electrochemical properties. These circulanes form stable (isolable) cation-radical salts upon 1-electron oxidation using antimony pentachloride and various aromatic oxidants.

A Simple Preparation of Benzo-Fused Bicycloalkadienes from 1,3-Diene-Benzoquinone Cycloadducts

Synthetic procedures are reported for the conversion of the Diels-Alder adduct of benzoquinone and both 1,3-cyclohexadiene and 1,3-cycloheptadiene to the parent hydrocarbons, 1,4-dihydro-1,4-ethanonaphthalene (benzobicyclooctadiene) and 6,7,8,9-tetrahydro-5H-5,9-ethenobenzocycloheptene (benzobicyclononadiene), respectively.The Diels-Alder adducts can be conveniently converted into the 5,8- and 1,4-dimethoxy as well as 5,8- and 1,4-diacetoxy derivatives, respectively, of these tricyclic compounds.

THE SYNTHESIS AND NMR CHARACTERIZATION OF A SERIES OF 1,4-DIHYDRO-1,4-ETHANONAPHTALENE EPOXIDES

A series of syn and anti epoxides derived from 5,8-disubstituted-1,4-dihydro-1,4-ethanonaphthalenes have been prepared.The role of the solvent on epoxidation stereochemistry has been explored.The structures of the epoxides were assigned with the aid of proton NMR coupled with chemical shift reagents.The C-13 spectra have also been assigned, and an unusual γ-effect of the epoxide structure noted.
