A total synthesis of (±)-isolongifolene (1) has been accomplished using intramolecular anionic cyclisation of the bromophenol 2 as the key step. Aryl participated intramolecular cyclisation of the diamethyl ketones 17 and 23 provided the dienediones 18 and 24 which were stereoselectively converted into the diketones 19 and 25 respectively.
