ResumoUnder dinuclear catalysis, the direct conjugate addition of 2(5H)-furanone to nitroalkenes involves the γ-position of the nucleophile. The synthetically versatile Michael adducts are prepared in good yields, with high levels of diastereo- and enantioselectivity. A model is presented to rationalize the observed stereoselectivity.
