69–92% yield by reductive dehalogenation of α-halo-β-arylbutenolides. The latter were assembled in a single-step from α,β-dihalobutenolides, which are accessible on a large-scale from biomass-derived furfural. Our dehalogenation protocol is illustrated by a new synthesis of the marineantibiotics rubrolide E and F, and 3″-bromorubrolide F.

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.
