Ginkgolide B is a diterpenoid isolated from Ginkgo biloba. The structural complexity and the biological properties of this natural product have fascinated chemists for decades.



Zinc homoenolate conjugate addition to A followed by cyclization yielded enone C. Conformational analysis led the authors to the discovery of a high-yielding photocycloaddition. Oxidative fragmentation and furan installation granted access to this intriguing molecule.
