Enantio- and diastereo-controlled synthesis of (+) - and (−) - eldanolide based on asymmetric pinacol-type rearrangement

Highly enantio- and diastereo-controlled synthesis of chiral pheromone, eldanolide, was accomplished in both enantiomeric forms, via organoaluminum-mediated asymmetric pinacol-type rearrangement followed by stereoselective reduction.
