Highly Efficient Ytterbium Triflate Catalyzed Michael Additions of α-Nitroesters in Water
31. Dezember 2000 (online)
Michael additions of α-nitroesters with enones and αβ-unsaturated aldehydes result in quantitative conversions to the corresponding 1,4-adducts by performing the reactions in water in the presence of ytterbium triflate as water-tolerant Lewis acid.
