We have previously shown that 4,5-diiodopentacyclo[4.3.0.02,4.03,8.05,7]nonane (1 ?) acts as a precursor to pentacyclo[4.3.0.02,4.03,8.05,7]non-4-ene (2 ) via dehalogenation with alkyllithiums, as 2  may be trapped as its Diels-Alder adduct 3  with diphenylisobenzofuran and other dienes. More recently, we have been investigating new methods for the synthesis of 4,5-diiodopentacyclo[4.3.0.02,4.03,8.05,7]nonane (1 ) as well alternative approaches to pentacyclo[4.3.0.02,4.03,8.05,7]non-4-ene (2 ), and we will report our progress in this area.
