Mono-C-alkylation of β-dicarbonyl compounds using tetraethylammonium fluoride

The hydrogen-bonded solvates formed between tetraethylammoniumfluoride and a number of β-dicarbonylcompounds react at about room temperature with alkyl iodides to provide high yields of the mono-C-alkylated β-dicarbonyl products with no apparent contamination due to the formation of O-alkyl, dialkyl, or polymerisation products.
Effect of the alkylating agent nature in the case of O- and C-alkylation of both ethyl acetoacetate and acetylacetonate anions is reported. The value of the O/C-ratio depends on three factors: the polar effect of the alkyl substituents in the alkylating agents, the steric effect of the alkyl groups and the symbiotic effect of the leaving groups. The relative contributions of the first two effects depends
one-pot procedure to achieve efficient DYKAT of α-substituted β-hydroxyketones. This newly developed protocol offers straightforward access to enantiomericallypure and diastereomerically enriched β-oxoacetates in high yields by employing a ruthenium-based racemization catalyst for efficient racemization-epimerization of substrates via formation of non-chiral 1,3-diketone intermediates.
