Abstract
The palladium-catalyzed allylic alkylation of non-stabilized ketone enolates was thought for a long time to be not as efficient as the analogous reactions of stabilized enolates, e. g. of malonates and β-ketoesters. The field has experienced a rapid development during the last two decades, with a range of new, highly efficient protocols evolved. In this review, the early developments as well as current methods and applications of palladium-catalyzed ketone enolate allylations will be discussed.

Abstract
Chelated ketone enolates are excellent nucleophiles for allylic alkylations. Electron-withdrawing groups on the allyl moiety allow subsequent intramolecular Michael additions giving rise to piperidines with up to five stereogenic centers.

Abstract
The miuraenamides, relatively simple representatives of a class of cyclodepsipeptides with high antitumor activity, can be easily and flexibly obtained by the concept of peptide modification. A reaction sequence consisting of an aldol reaction, oxidation, and methylation of the glycine subunit of the cyclodepsipeptides allows the incorporation of the unusual α,β-unsaturated dehydroamino acid in one of the last steps of the synthesis.

Abstract
Chelated amino acid ester enolates are excellent nucleophiles for ruthenium-catalyzed allylic alkylations. Although [Cp*Ru(MeCN)3 ]PF6 was found to be the most reactive catalyst investigated, with the resulting allyl complexes reacting at temperatures as low as -78 °C, unfortunately the process took place with only moderate regio- and diastereoselectivity. In contrast, [(p-cymene)RuCl2 ]2 allowed allylations to be performed with a high degree of regioretention. Secondary allyl carboxylates with a terminal double bond were found to be the most reactive substrates, giving rise to the branched amino acids with perfect regioretention and chirality transfer. In this case, no isomerization of the Ru-allyl complex formed in situ was observed, in contrast to the analogues palladium complexes. This isomerization-free protocol can also be used for the synthesis of (Z)-configured γ,δ-unsaturated amino acid derivatives, starting from (Z)-allylic substrates. Here, the more reactive phosphates were found to be superior to the carboxylates, providing the required amino acids in almost quantitative yield with perfect regio- and stereoretention. Therefore, the Ru-catalyzed allylation reactions are well positioned to overcome the drawbacks of Pd-catalyzed processes.

Abstract
Acylsilanes as a new type of "hard" carbon prenucleophile reacted with monosubstituted allyl reagents under Pd-catalyzed asymmetric allylic alkylation reaction conditions to provide products with high regio-, diastereo-, and enantioselectivities. The usefulness of the protocol has been demonstrated by the ready conversion of the allylated products into the corresponding alcohols, esters, and ketones with retention of stereochemistry as well as by the enantioselective synthesis of cis-3-ethyl-4-phenylpiperidine and cinnamomumolide.

Abstract
The kinetic resolution of a carbon nucleophile is realized for the first time via Pd-catalyzed asymmetric allylic alkylation with "unstabilized" ketone enolates as the nucleophile, providing both allylated 2,3-disubstituted 2,3-dihydro-4-quinolones and recovered substrates in high yields and high ee (S-factor is 40-145). The application of the methodology in organic synthesis is demonstrated by the ready transformation of an allylated adduct into pyrrolo[3,2-c]quinoline, which features a core structure of biologically active Martinella alkaloids.
