Conjugate addition of the lithium dienediolate derived from crotonic acid to several α,β-unsaturated ketones gave 7-oxocarboxylic acids.Styryl ketones (2a-g) afforded mixtures of 1,4-α- and 1,4-γ-adducts, in proportions depending on the bulk of the substi

Michael addition of the dienolate derived from 2-butenoic acid to 1,3-diphenylpropenone occurs through a 1,2-addition followed by a -sigmatropic rearrangement, α,γ-regioselectivity found for Michael addition to other styryl ketones depends on the ste
