complex secondary metabolite epicolactone is a member of the natural product pool found in cash crop endophytes of the genus Epicoccum. By exploiting inherent reactivity, a totalsynthesis of this highly oxygenated and polycyclic molecule met chemo‐ and regioselectivity challenges. The key buildup of complexity was accomplished via an intramolecular [2+2] photocycloaddition between a quinone and an

cytotoxic (Z)-5-ylidene-2(5H)-furanone derivatives, has been conveniently prepared from 3,4-di-bromo-2(5H)-furanone by a three-step proccdure involving two Pd-catalyzed cross-coupling reactions and a Rh(I)-catalyzed hydrogenation.
