[GRAPHICS]Appropriate enediols experience a one-pot palladium(II)-mediated hydroxycyclization-carbonylation-lactonization sequence to provide sidechain-functionalized 2,6-dioxabicyclo[3.3.0]octan-3-ones, the core structures of the plakortones, a novel class of activators of cardiac SR-Ca2+-pumping ATPase, from the sponge Plakortis halichondrioides.

A palladium(II)-catalyzed hydroxycyclization-carbonylation-lactonization sequence with appropriate pent-4-ene-1,3-diols provides efficient access to the bicyclic gamma-lactones, 5-n-butyl- and 5-n-hexyltetrahydrofuro-[3,2-b]furan-2(3H)-ones (3) and (4), respectively, in both racemic and enantiomeric forms. Some of the substrate pent-4-ene-1,3-diols of high enantiomeric excess (ee) have been derived

continuous flowcarbonylationreaction using iron pentacarbonyl as source of CO. The described transformation using this surrogate was designed for use in commonly accessible flow equipment. Optimized conditions were applied to a scalable synthesis of the natural compound isolated from perianal glandular pheromone secretion of the African civet cat. In addition, a flowPd-catalyzedcarbonylation of aryl
