The biomimetic total synthesis of penifulvins B and C uses a meta-photocycloaddition as a key step which gives rapid access to the fenestrane-type carboskeleton with control of an onring quaternary stereocenter. The route Is concise, stereocontrolled, scaleable, and flexibile and requires only one protecting group.
