Cyclization of the (3-methylenecyclohexyl)ethyl radical (9) to the isomeric 1-bicyclo[3.2.1]octylmethyl radical(10) occurs with an activation energy of 11.6 kcal mol(-1), a barrier which compares favorably with the calculated value of 12.6 kcal mol(-1) determined by force field calculations. It is shown that the facility for ring closure of 9 can be exploited for high-yield synthesis of bicyclo[3.2.1.]octanes with useful functionality at the bridgehead including the preparation of models of the bicyclo[3.2.1]octyl moiety in the gibberellin sytem.
