Crosswise ring closures in bicyclo[2.2.2]octene or bicyclo[2.2.2]octane systems were studied in order to construct an oxatwistane frame. An entry into the oxatwistane system could be achieved by either crosswise etherization of a methylbicyclooctene-methanol(20) with 12N-HCl/EtOH or intramolecular dehydration of a hydroxy-methylbicyclooctane-methanol(25).
