Concise diastereoselective syntheses of the marine (+/-)-panacene and terrestrial (+/-)-desbromopanacene have been achieved in a few steps based on a concept of "aromatic ring umpolung". The synthetic avenue to the (+/-)-panacene involved a novel oxymercuration strategy to produce the correct configuration of the bromoallene moiety.
