摘要：
beta-Lactones are common substructures in bioactive molecules. Herein, we developed an enantioselective N-heterocyclic carbene (NHC)-catalyzed rearrangement of enol epsilon-lactones for the construction of bicyclic beta-lactones. The reaction works well for both exo- and endo-enol epsilon-lactones, giving the corresponding bicyclic beta-lactones with two or three contiguous stereocenters, respectively. The reaction features readily available starting materials, 100% atom economy, mild conditions, high diastereo- and enantioselectivity.
