摘要：
Not a cop out: The copper-catalyzed asymmetric conjugate addition of organometallic reagents to Michael acceptors is an important methodology for forming a C-C bond in an enantioselective manner. Such an addition of Me 3Al to β,γ-unsaturated α-ketoesters is described to proceed in high yield and selectivity. CuTC=copper(I) thiophene-2-carboxylate. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
