The nucleophilic phosphine-catalyzed diastereoselective iodocyclization of linear isoprenoids bearing an oxygen terminal group was investigated. TBDMS ether of homogeraniol and TBDMS ester of homogeranic acid were successfully converted to the corresponding iodopolycyclic products in the presence of a catalytic amount of triphenylphosphine with complete diastereoselectivity.
