Transition-metal-free formal decarboxylative coupling of ?±-oxocarboxylates with ?±-bromoketones under neutral conditions: A simple access to 1,3-diketones

A transition-metal-free formal decarboxylative coupling reaction between ?±-oxocarboxylates and ?±-bromoketones to synthesize 1,3-diketone derivatives is presented. In this reaction, a broad scope of substrates can be employed, and neither a metal-based reagent nor an additional base is required. DFT calculations reveal that this reaction proceeds through a coupling followed by decarboxylation mechanism and the ?±-bromoketone unprecedentedly serves as a nucleophile under neutral conditions. The rate-determining step is an unusual hydrogen-bond-assisted enolate formation by thermolysis.

High-yielding oxidation of β-hydroxyketones to β-diketones using o-Iodoxybenzoic acid

The oxidation of β-hydroxyketones to β-diketones was systematically investigated. o-Iodoxybenzoic acid (IBX) was found to be efficient, operationally easy, and superior to other common oxidants. The reaction is suitable for milligram- to gram-scale oxidations.

Enantioselective borohydride reduction catalyzed by optically active cobalt complexes

The highly enantioselective borohydride reduction of aromatic ketones or imines to the corresponding alcohols was developed in the presence of a catalytic amount of an optically active cobalt(II) complex catalyst. This enantioselective reduction is carried out using a precisely premodified borohydride with alcohols such as tetrahydrofurfuryl alcohol, ethanol and methanol. High optical yields are obtained by choosing the appropriate alcohol as modifiers and a suitable β-ketoiminato ligand of the catalyst. The enantioselective borohydride reduction has been successfully applied to the preparation of optically active 1,3-diols, the stereoselective reduction of diacylferrocenes, and dynamic and/or kinetic resolution of 1,3-dicarbonyl compounds.

A novel synthesis of 1,3-diketones by reaction of an α-bromoketone with acyl chlorides promoted by gallium triiodide

Promoted by gallium triiodide, an α-bromoketone, bromomethyl phenyl ketone, is treated with acyl chlorides to synthesize 1,3-diketones in good yields under mild and neutral conditions.

An alternative route to 1,3-diketones promoted by samarium diiodide

Sml2 promoted condensation of α-haloketones with carboxylic acid chlorides or anhydrides leads to 1,3-diketones.

β-Diketone synthesis by reaction of α-haloketones with acid chlorides or acid anhydrides promoted by samarium triiodide

Promoted by SmI3, α-haloketones were reacted with acid chlorides or acid anhydrides and β-diketones were synthesized via intermediate samarium enolates.
