The effectiveness of two different reaction media, an ionic liquid (IL) and a deep eutectic solvent (DES), as greener, alternative solvents for the synthesis of bioactive bis-(β-dicarbonyl)-methane derivatives I [R1 = H, OH, OMe, Cl; R2 = H, OH, OMe; R3 = H, Cl; X = O, NH, NMe] was examined A domino Knoevenagel-Michael reaction between aromatic aldehydes and heterocyclic 1,3-dicarbonyl compounds was successfully accomplished, producing the desired compounds I in satisfactory yields. The solvents were recycled and reused three times without noticeable decrease in reaction yields. A putative conformation of compound I [R1 = OMe, R2 = R3 = H, X = NMe] was determined using NMR spectroscopy and an ”anti” orientation of the fused aromatic rings was proposed. Moreover, some of the bis-(β-dicarbonyl)-methane derivatives I were tested for their antifungal activity against four Candida albicans strains. The biscoumarin I [R1 = H, R2 = R3 = OMe, X = O] and bisquinolinone I [R1 = OH, R2 = OMe, R3 = H, X = NMe] exhibited promising anticandidial activity. In parallel, in silico ligand-based similarity calculations provided a putative mechanism of action of the examined compounds through CYP51 inhibition.

Barysevich, Maryia V. published the artcilePalladium-Catalyzed 2-(Neopentylsulfinyl)aniline Directed C-H Acetoxylation and Alkenylation of Arylacetamides, Formula: C9H10O3, the main research area is aryl acetamide regioselective acetoxylation diacetoxyiodobenzene palladium catalyst; acetoxy arylacetamide preparation; cyclopropanol stereoselective regioselective alkenylation arylacetamide palladium catalyst; alkenyl arylacetamide preparation.

The 2-(neopentylsulfinyl)aniline directing group that promotes rapid palladium-catalyzed C-H acetoxylation and alkenylation of arylacetamides has been developed. The acetoxylation reached completion within only 40 min at 100°C and led to the bis-functionalized products. Alternatively, the reaction can be carried out at room temperature, which is beneficial for sensitive substrates. For the alkenylation, a protocol has been developed where easily available 1-substituted cyclopropanols were employed as equivalent of vinyl ketones.

A new iron-organic framework, VNU-22 ̅{[Fe3(BTC)(BPDC)2].11.97H2O}, constructed from BTC3-, BPDC2-pillars and infinite [Fe3(CO2)7]∞rod SBU, was obtained. The VNU-22 was utilized as a heterogeneous catalyst in the synthesis of 2,4,6-triphenylpyridines via cascade reactions from acetophenones and phenylacetic acids with ammonium acetate as a nitrogen source. The VNU-22 was more active in the cascade reactions than many homogeneous and heterogeneous catalysts. The framework catalyst was recovered and reutilized without an appreciable decline in its performance. To our best knowledge, this synthetic pathway to 2,4,6-triphenylpyridines was not previously reported and would attract interests from the chem. industry.

Zhao, Mingsheng published the artcileSynthesis, characterization, and DRAK2 inhibitory activities of hydroxyaurone derivatives, Safety of 2,3-Dimethoxybenzaldehyde, the main research area is hydroxyaurone preparation DRAK2 inhibitor SAR.

Authors reported the synthesis of 25 derivatives of hydroxyaurone which were characterized by 1H NMR, 13C NMR, high resolution mass spectrum, and single crystal X-ray diffraction anal. Their activities on the death-associated protein kinase-related apoptosis-inducing kinase-2 (DRAK2) were evaluated by kinase detection kit at a dosage of 5μM. Most of the synthetic hydroxyaurones exhibited moderate to good inhibitory activities. The IC50 value ranged from 0.81 to 2.42μM when the structure of aurone’s B ring was kept unchanged and its A ring was substituted by hydroxyl groups. On the contrary, modification of the aurone’s B-ring with hydroxyl groups lead to the IC50 value ranging from 1.15 to 17.5μM. This indicates presence of hydroxyl group of the B ring is crucial for aurone’s DRAK2 kinase inhibitors. Therefore, hydroxyaurone may serve as a new possible lead compound for the discovery of DRAK2. Further pharmacol. investigations are underway and will be reported in due course.
