[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.
