An efficient synthetic route was developed to prepare substituted δ-lactones 1 and 2 in enantiopure forms which are potentially useful for biosynthetic studies with genetically engineered modular polyketide synthase (PKS). The key step to prepare the target epimeric lactones involves the samarium(II) iodide-mediated Reformatsky reaction.
