Intramolecular ene reaction on a bicyclo[3.2.1]octane system: An alternative route to (-)-kainic acid

The intramolecular ene reaction of the 1,6-diene on a bicyclo[3.2.1]octane framework proceeds in a highly diastereoselective manner to form a trisubstituted pyrrolidine on the pyran ring in excellent yield. Its stereochemistry has been determined unambiguously by converting it into the known compound serving as a key intermediate of (-)-kainic acid.
