Bilobalide is a tetracyclic sesquiterpene containing three contiguous γ‐lactone rings and an unusual tert‐butyl group, which is found in the leaves of the ginkgo tree (Ginkgo biloba). Three different photochemical approaches towards bilobalide's unique skeleton are presented. A meta photocycloaddition, a [2 + 2] photocycloaddition, and a Paternò–Büchi‐reaction were chosen as the respective key steps.
The synthesis of the tetracyclic core of bilobalide was attempted by using three different photochemical approaches: A meta photocycloaddition, a [2+2] photocycloaddition of an enone to an allenyl ether, and a Paternò–Büchi reaction of a ketone to a furan. While none of the procedures could be taken to the final target structure, the rapid assembly of highly functionalized intermediates was achieved.
