We report herein the enantioselectiveCu-catalyzed conjugate addition of organometallic reagents to sensitive Michael acceptors and their application to the synthesis of relevant target molecules. This is one of the most important methodologies to form a C-C bond in an enantioselective manner. A wide range of alpha,beta-unsaturated aldehydes and beta,gamma-unsaturated-alpha-ketoesters has been successfully

Not a cop out: The copper‐catalyzed asymmetric conjugateaddition of organometallic reagents to Michael acceptors is an important methodology for forming a CC bond in an enantioselective manner. Such an addition of Me3Al to β,γ‐unsaturatedα‐ketoesters is described to proceed in high yield and selectivity. CuTC=copper(I) thiophene‐2‐carboxylate.
