Diels-Alder reactions of 2′-hydroxychalcones with ortho-benzoquinodimethane: A new synthesis of 3-aryl-2-naphthyl 2-hydroxyphenyl ketones

Diels-Alder reactions of the 2′-hydroxychalcones 1a-e with oriho-benzoquinodimethane (3) yielded the 3-aryl-1,2,3,4-tetrahydro-2-naphthyl 2-hydroxyphenyl ketones 4a-e in good yields. The dehydrogenation of the cycloadducts 4a-e to 3-aryl-2-naphthyl 2-hydroxyphenyl ketones 5a-e was studied. Good results were obtained when DDQ was used as oxidant and microwave irradiation as energy source. Several benzoxanthone derivatives were also obtained as minor products. Structures of all new compounds were established by extensive NMR studies. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Impact of Solvent and Their Contaminants on Pd/C Catalyzed Suzuki-Miyaura Cross-Coupling Reactions

The aim of this work was to understand if solvent contaminants can interfere in Suzuki’s cross-coupling reactions and if it can explain the lack of robustness in industrial processes. For this purpose, several parameters were tested on the industrial model reaction between 2-bromonaphthalene and phenylboronic acid catalyzed by Pd/C. Best results were obtained using THF as solvent. Traces of the precursors of the used solvents, such as 2,3-dihydrofurane or maleic anhydride (100–300 ppm related to the solvent) strongly poisoned the reaction, decreasing the conversion significantly. This means that to ensure robust production, solvent quality must be analyzed at the ppm level. Fortunately, addition of triphenylphosphine can circumvent the catalyst poisoning.

Arylketones as Aryl Donors in Palladium-Catalyzed Suzuki-Miyaura Couplings

Herein, we report the arylation, alkylation, and alkenylation of aryl ketones via a palladium-catalyzed Suzuki-Miyaura cross-coupling reaction. The use of the pyridine-oxazoline ligand is the key to the cleavage of the unstrained C-C bond. The late-stage arylation of aryl ketones derived from drugs and natural products demonstrated the synthetic utility of this protocol.

Nickel-Catalyzed Amination of Aryl Chlorides with Amides

A nickel-catalyzed amination of aryl chlorides with diverse amides via C-N bond cleavage has been realized under mild conditions. A broad substrate scope with excellent functional group tolerance at a low catalyst loading makes the protocol powerful for synthesizing various aromatic amines. The aryl chlorides could selectively couple to the amino fragments rather than the carbonyl moieties of amides. Our protocol complements the conventional amination of aryl chlorides and expands the usage of inactive amides.
