The putative common precursor to siphonarin B, baconipyrone A, baconipyrone C, and caloundrin B was prepared by an enantioselective total synthesis featuring our thiopyran route to polypropionates strategy. In the presence of imidazole, the precursor

The hypothesis that siphonariid polypropionates originate from nonenzymatic processes on acyclic biosynthetic precursors was tested by examining the properties of the putative common precursor for the S. zelandica decapropionates siphonarin B, caloun
