Abstract
The europium(III) complex, Eu(dppm)3, is found to be an efficient catalyst for the Michael reactions of α, β- enones with ketene silyl acetals. The high level of erythro selectivity obtained in the reaction of tert-butyl (E)- propenyl ketones (2c) with (E)-1-tert-butoxy-1-[(trimethylsilyl)oxy]propene (3d) is rationalized on the basis of the LIS-NMR analysis of the europium(III) catalyst/enone 2c complex.
