Two different 6-exo-trigonal cyclizations of enantiomerically enriched 6-heptenyl radicals readily afforded versatile synthetic precursors of cis-1,2-dialkyl substituted cyclopentane derivatives. Starting from one of these intermediates, we accomplished an enantiospecific formal synthesis of two important isoprostanes, namely 15-F-2c-IsoP and ent-15-F-2c-IsoP. (C) 2001 Elsevier Science Ltd.
