A general intermolecular anti-Michael reductive Heck reaction of alpha,beta-unsaturated esters with organobromides has been developed. Most topical classes of aryl, heteroaryl, and vinyl bromides were found to efficiently react with a variety of internal conjugated alkenes. This protocol set up a platform toward diverse alpha-arylated 1,6-dicarbonyl frameworks found in natural products and drugs, which are still highly challenging targets in traditional alpha-arylation protocols because of competitive selectivity of enolation. A removable directing group, gram-scale reaction, and modification of complex molecules have additionally demonstrated that the anti-Michael reductive Heck reaction is a powerful complementary strategy to the classical alpha-arylation approaches. Preliminary mechanistic studies are consistent with our proposed mechanistic design.

Polyaniline coated on particles of celite is used as support to load palladium catalyst. This heterogenized Celite center dot PANI center dot Pd system, is used as an efficient catalyst for chemoselective hydrogenation reactions. The catalyst is characterized by usual spectral, analytical techniques and studied for hydrogenation reactions at ambient conditions. The mild reaction conditions allow the control over the reactions and excellent selectivity is achieved in number of conversions. Hydrogenation of a carbon-carbon double bond was favored over other polar pi-bond systems, while labile functional groups such as benzyl ether, benzyl esters, cyano, nitro and halogen remained unaffected. Primary amines were converted to N,N-dimethyl amines with formaldehyde, the double bond of coumarin was selectively hydrogenated without opening of the lactone functionality.

Application In Synthesis of Chalcone. Argouarch, G in [Argouarch, Gilles] Univ Rennes, CNRS, UMR 6226, ISCR, F-35000 Rennes, France published Mild and efficient rhodium-catalyzed deoxygenation of ketones to alkanes in 2019.0, Cited 33.0. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

A new and simple method for the deoxygenation of ketones to alkanes is presented. Most substrates are reduced under mild conditions by triethylsilane in the presence of catalytic amounts of [Rh(mu-Cl)(CO)(2)](2). This system selectively provides the methylene hydrocarbons in good to excellent yields starting from acetophenones and diaryl ketones. A rapid examination of the reaction pathway suggests that the ketone is first converted into an alcohol, which then undergoes hydrogenolysis to give the alkane.

Regioselectivity is a crucial issue in Baeyer-Villiger (BV) oxidation. To date, few reports have addressed asymmetric BV oxidation of 3-substituted cycloketones due to the high difficulty of controlling regio- and stereoselectivity. Herein, we report the asymmetric BV oxidation of 3-substituted and meso-disubstituted cycloketones with chiral N,N ‘-dioxide/Sc(iii) catalysts performed in three ways: classical kinetic resolution, parallel kinetic resolution and desymmetrization. The methodology was applied in the total and formal synthesis of bioactive compounds and natural products. Control experiments and calculations demonstrated that flexible and adjustable catalysts played a significant role in the chiral recognition of substrates.

The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Delta(2)-pyrazoline analogs as novel Hsp90 inhibitors by integrated approaches of drug design, organic synthesis, cell biology, and qualitative proteomic analysis. Novel chemical compounds were designed and optimized in the adenosine triphosphate-binding site of Hsp90; lead optimized compounds were found to have significant interactions with Asp93 and other amino acids crucial for Hsp90 inhibition. The designed compounds were synthesized by a two-step procedure; different aromatic aldehydes were reacted with various acetophenones to form substituted 1,3-diphenyl-prop-2-enones (Ic-Io), which upon reaction with isonicotinic acid hydrazide in the presence of glacial acetic acid form N-pyridoyl-Delta(2)-pyrazoline compounds (PY1-PY13). Compounds PY3, PY2, and PY1 were identified as potential leads amongst the series, with promising anticancer activity against human breast cancer and melanoma cells, and the ability to inhibit Hsp90 similar to radicicol by drug-affinity responsive target stability proteomic analysis in a whole-cell assay.

An olefinic difunctionalization method of enones was presented hereviaaerobic visible-light catalysis. A novel reactivity was showcased in conjunction with the selective Csp(2)-C(CO) bond activation of enones, which provided a convenient method for the preparation of various beta-thiolated-alpha-functionalized compounds. Moreover, the preliminary investigation of the mechanism indicated that a beta-peroxysulfide intermediate was formed under the promotion of visible light under an oxygen atmosphere, which finally induced the unexpected C-C bond cleavage.

An article Abscisic acid and stress induced by salt: Effect on the phenylpropanoid, L-ascorbic acid and abscisic acid metabolism of strawberry fruits WOS:000536123200021 published article about FRAGARIA-X-ANANASSA; PHENYLALANINE AMMONIA-LYASE; TIME-QUANTITATIVE PCR; DIFFERENT CULTIVARS; GENE-EXPRESSION; DROUGHT STRESS; TOLERANCE; PROLINE; PLANT; MECHANISMS in [Crizel, R.

Strawberry is one of the most popular fruits because of its sensorial and functional properties. However, strawberry crop is sensitive to salt stress conditions. Despite plants have plasticity, high salt concentrations induce molecular, biochemical, and physiological responses in plants. There is evidence that the abscisic acid (ABA) hormone acts as a signaling molecule under stress conditions; however, the molecular mechanisms involved in the synthesis and homeostasis of ABA and in the induction of phytochemical antioxidant compounds under stress conditions remain unclear. In this study, the effect of stress induced by NaCl (salt stress – SS), with or without the simultaneous application of ABA, on the ABA, phenylpropanoids and L-ascorbic acid (AsA) metabolisms were evaluated. The physiological aspects (Na, Cl and proline concentration, photosynthetic variables) were also studied. The results showed that salt stress increases the Na and Cl content in the leaves, affects photosynthetic variables and triggers the production of proline, pelargonidin-3-O-glucoside, total phenolic compounds and AsA content, alongside the upregulation of several genes from the phenylpropanoid and flavonoid pathways. These effects were accompanied by the induction of compounds and transcripts related to ABA biosynthesis, conjugation and catabolism. Otherwise, the exogenous application of ABA in salt stressed plants promotes a shift in gene expression and metabolism to mitigate the stress. Therefore, salt stress affects the metabolism of ABA, phenylpropanoids and AsA in strawberry increasing phytochemical composition which is strongly associated with an ABA-dependent mechanism.
