Blum, Stephan P. published the artcileMetal-Free Electrochemical Synthesis of Sulfonamides Directly from (Hetero)arenes, SO2, and Amines, COA of Formula: C2H6N2O, the main research area is sulfonamide dehydrogenative electrochem synthesis heteroarene amine; electrochemistry; green chemistry; oxidation; radical reactions; sulfonamides.

Sulfonamides are among the most important chem. motifs in pharmaceuticals and agrochems. However, there is no methodol. to directly introduce the sulfonamide group to a non-prefunctionalized aromatic compound Herein, we present the first dehydrogenative electrochem. sulfonamide synthesis protocol by exploiting the inherent reactivity of (hetero)arenes in a highly convergent reaction with SO2 and amines via amidosulfinate intermediate. The amidosulfinate serves a dual role as reactant and supporting electrolyte. Direct anodic oxidation of the aromatic compound triggers the reaction, followed by nucleophilic attack of the amidosulfinate. Boron-doped diamond (BDD) electrodes and a HFIP-MeCN solvent mixture enable selective formation of the sulfonamides. In total, 36 examples are demonstrated with yields up to 85%.

Verma, Vibha published the artcileQuinolinium chlorochromate: an excellent reagent for N3-C4 dehydrogenation of dihydropyrimidinones and their antifungal evaluation, SDS of cas: 598-50-5, the main research area is pyrimidinone green preparation antifungal SAR; dihydropyrimidinone preparation antifungal SAR oxidation quinolinium chlorochromate; benzaldehyde ketoester urea Biginelli hydrochloric acid catalyst.

3,4-Dihydropyrimidin-2-ones (DHPMs) I [R1 = Ph, 3-HOC6H4, 2-O2NC6H4, etc.; R2 = Me, Et, i-Pr; R3 = H, Me] were synthesized by reaction of aromatic aldehydes, β-ketoester and urea/N-Me urea. These compounds I on oxidation with quinolinium chlorochromate as an oxidizing agent resulted into pyrimidin-2-ones II. The synthesized compounds I and II were screened against three test fungi of wheat crop, i.e., Alternaria triticina, Bipolaris sorokiniana and Ustilago segetum tritici by spore germination method. Compounds II showed excellent antifungal activity than compounds I with least ED50 values 42, 93 and 47 μg/mL. Among the tested compounds, compounds II [R1 = 4-O2NC6H4, R2 = i-Pr, R3 = H; R1 = 2,4-di-MeOC6H3, R2 = Et, R3 = Me] were found to be most active. Structure activity relationship showed that electron withdrawing group enhanced their efficacy due to +I effect and vice versa, whereas dehydrogenation improved their potential due to resonance stabilization of structures involved during electronic interactions between proteins of fungus cells and compounds

Wang, Zhaogai published the artcileConcentrating sulphur-containing flavour from Toona sinensis shoots using corn oil with and without aqueous dispersion, Application In Synthesis of 1455-77-2, the main research area is Toona sinensis flavor corn oil.

Toona sinensis (TS) shoot is a seasonal and quick deteriorating vegetable with unique alliaceous flavor. In this study, corn oil was used to concentration the sulfur-containing compounds responsible for the unique TS flavor with and without aq dispersion. The level of sulfur-containing compounds in TS shoots was 0.32μg g-1 and concentratio to 2.34μg g-1 in the corn oil with aq dispersion. The sulfur-containing compounds, trans-2-Mercapto-3,4-dimethyl-2,3-dihydrothiophene and (E,Z)-Di-1-propenyldisulfide, were identified in the corn oil, while they were not detected in the oil without aq dispersion. Based on sensory and electronic nose anal., the aroma of corn oil with aq medium extraction had stronger alliaceous aroma than TS shoots and the extraction corn oil without aq dispersion. With aq dispersion assistance, the sulfur-containing aroma compounds in TS shoots were effectively concentration in corn oil. The flavor-enriched oil could serve as a flavor ingredient to deliver TS shoots aroma for different food applications.

Zhen, Zong-Yuan published the artcileDetermination of volatile flavor compounds in raw and treated duck meats of different body parts, Computed Properties of 1455-77-2, the main research area is volatile flavor compound body part duck meat; duck meat; gas chromatography-mass spectrometry (GC-MS); headspace solid-phase micro-extraction (SPME); volatile flavor substance.

The compounds in volatile flavor substances in duck meats of three different body parts (breast, leg, and wing) were extracted by headspace solid-phase micro-extraction and determined by gas chromatog.-mass spectrometry. A total of 16 main volatile compounds including 4 hydrocarbons, 4 alcs., 2 acids, 3 aldehydes, and 3 others (N-containing, S-containing) were identified in raw duck meats from three different body parts. The hydrocarbon compounds account for more than 50% of all volatile substances in all three body parts. And the percentage of hydrocarbon compounds in raw duck breast meat reaches 82.76%. A total of 81 volatile compounds including 15 hydrocarbons, 10 alcs., 7 acids, 12 aldehydes, 4 esters, 19 S-containing and N-containing compounds, and 14 others were isolated and identified in 1 h-marinated and cooked duck meats. A total of 101 kinds of volatile flavor compounds including 13 hydrocarbons, 14 alc., 7 acids, 8 aldehydes, 12 esters, 23 S-containing and N-containing compounds, and 24 others were detected in 3 h-marinated duck meats of the three body parts. It was proved in this study that under the same conditions, the volatile compounds in duck legs are more than those in duck breasts and wings, and the types of volatile flavor substances increase significantly in duck meats after cooked. Practical applications Prepared and cooked duck meat, especially wings and legs are popular food in China. The results suggest that Pickling makes duck meat more flavory while proper pickling time is less than 3 h. Duck wings are better for marinating and cooking compared with duck breasts and legs. The acceptance study of duck meat from different body parts and the anal. of volatile flavor compounds are beneficial for optimizing utilization of whole parts of duck meat.

Bian, Yinghui published the artcileUnderstanding the oxidation and reduction reactions of sulfur in rechargeable aluminum-sulfur batteries with deep eutectic solvent and ionic liquid electrolytes, Application In Synthesis of 598-50-5, the main research area is aluminum sulfur secondary battery deep eutectic solvent; ionic liquid electrolyte; aluminum-sulfur batteries; deep eutectic solvents; electrolytes; ionic liquids; oxidation.

Al-based batteries are promising next-generation rechargeable batteries owing to the abundance of raw materials and their high potential energy d. The Al-S system has attracted considerable attention because of its high energy d. and low cost. However, its low discharge voltage plateau (0.6-1.2 V) hampers its practical application. Herein, eight ionic liquids or deep eutectic solvents were studied as electrolyte candidates for an Al-S cell. This was the first study to demonstrate that an Al-S cell based on an AlCl3/acetamide electrolyte (1.3 molar ratio) showed high discharge voltage plateaus (1.65-1.95 V) and a charging cut-off voltage of 2.5 V in Al-S cells. An Al-S cell of 0.33 mAh capacity with the AlCl3/acetamide electrolyte successfully lit up a red LED (forward voltage 1.6-2.0 V) for around 2 h. This work may help in promoting the development of high-performance and low-cost Al-S cells.
