(+)-Pisiferic acid (1), an antibiotic active against Gram-negative and Gram-positive bacteria, was synthesized starting from dehydroabietic acid (2) or abieticacid (26). The terpene ring system was functionalized and a Barton reaction used to oxidize Me(20). The intermediates of this photochemicalreaction were isolated and characterized.
