A novel approach to the Geissman-Waiss lactone and a key intermediate in the synthesis of pyrrolidine trans-lactones

Based on the highly regio- and diastereoselective reductive- ethoxycarbonylmethylation of protected (S)-malimide 4, a new approach to the Geissman-Waiss lactone 1 and a key intermediate 3 for the synthesis of pyrrolidine trans-lactones (e.g., 2) is descri
