Significance

The authors report a silver(I)-mediated diastereoselective synthesis of γ-butenolide and γ-lactone products. Chiral phosphine-oxazole ligands were found to provide high diastereoselectivities for a variety of fluorinated aldimines. The products were found to be amenable to reduction and/or further derivatization.
