The asymmetric synthesis of (−)-dihydrosporothriolide (1), a biologically active bis-γ-butyrolactone, is described, that proceeds through ad-proline-catalyzed asymmetric aminooxylation, indium-mediated Reformatsky–Claisen rearrangement of an α,α-dibromoacetate derivative, and diastereoselective dihydroxylation. The route requires no protective group manipulation and allows the concise seven-step synthesis of1fromn-octanal.
