Electric Literature of 4265-16-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4265-16-1, Benzo[b]furan-2-carboxaldehyde, introducing its new discovery.

Benzofurans can undergo ring-opening by a palladium-catalyzed process resulting in C?O bond breaking. Benzofuran-tethered 2-iodoanilines give synthetically interesting 2-(3-indolylmethyl)phenols in an overall reductive process. Mechanistic studies suggest that this unusual reaction proceeds by carbopalladation of benzofuran giving a 3-palladated 2,3-dihydrobenzofuran intermediate, which then fragments by an uncommon trans-elimination of the phenoxide group beta to the metal. In this transformation, N,N-diisopropylethylamine (DIPEA) acts as a base and as a reducing agent: it regenerates palladium(0) from palladium(II), thus allowing catalytic turnover. (Figure presented.).

Application of 4265-16-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4265-16-1, molcular formula is C9H6O2, introducing its new discovery.

Facile synthesis of natural aurones, rugaurone A (1a), gramflavonoid A (1b) and their novel derivatives (1c-1o) is accomplished in good to high yields with exceptional Z-selectivity (? 97%) from the commercially available starting materials. Herein, practically improved method was developed for the synthesis of common key intermediate, 5,6-dimethoxybenzofuran-3(2H)-one (5). Later, their nitric oxide (NO) production inhibition effects were estimated in lipopolysaccharide (LPS)-induced RAW-264.7 macrophages as an indicator of anti-inflammatory activity. All compounds exhibited weak to good strength against NO production in a concentration-dependent manner and none of the compound showed significant cytotoxicity against macrophages at the highest (10 muM) concentration. The IC50 values are showed in the range from 3.39 to 19.55 muM. Among the 15 aurones synthesized in this study, 3 compounds that is compound 1g (63.98%) followed by compound 1o (49.07%) and rugaurone A (1a) (41.72%) showed the maximum inhibitory activity with respective IC50 values of 4.50 muM, 4.98 muM and 3.39 muM compared to L-NMMA (IC50 = 5.19 muM), which was used as a standard NO inhibitor. This study suggests that compounds 1g, 1o and 1a may serve as favorable structures for further development of NO production-targeted anti-inflammatory agents.

Four novel series of cinnamyl-containing histone deacetylase (HDAC) inhibitors 1-4 are described, containing hydroxamate (1 and 3) or 2-aminoanilide (2 and 4) derivatives. When screened against classI (maize HD1-B and human HDAC1) and classII (maize HD1-A and human HDAC4) HDACs, most hydroxamates and 2-aminoanilides displayed potent and selective inhibition toward classI enzymes. Immunoblotting analyses performed in U937 leukemia cells generally revealed high acetyl-H3 and low acetyl-alpha-tubulin levels. Exceptions are compounds 3f-i, 3m-o, and 4k, which showed higher tubulin acetylation than SAHA. In U937 cells, cell-cycle blockade in either the G2/M or G1/S phase was observed with 1-4. Five hydroxamates (compounds 1h-l) effected a two- to greater than threefold greater percent apoptosis than SAHA, and in the CD11c cytodifferentiation test some 2-aminoanilides belonging to both series 2 and 4 were more active than MS-275. The highest-scoring derivatives in terms of apoptosis (1k, 1l) or cytodifferentiation (2c, 4n) also showed antiproliferative activity in U937 cells, thus representing valuable tools for study in other cancer contexts.

A series of linear benzofuran derivatives consisting of either a vinylene or a cyanovinylene were prepared in order to investigate their emission properties. The X-ray crystallography of structurally similar derivatives was also evaluated. The crystalline structures of the vinylene derivatives showed only lateral contacts that involved the benzofurans and no pi-stacking. In contrast, pi-stacking was observed for the bisbenzofuran and benzofuran-phenyl cyanovinylene derivatives. No intermolecular pi-pi stacking was observed for the extended cyanovinylene structures. Intermolecular bonding between the nitrile and a furan atom was found. The fluorescence quantum yields (fl) of the vinylene derivatives were consistently high (>50%) in both solution and the crystal state. The exception was the benzofuran-furan-vinylene-phenyl, the fl of which was <10% when in the solid state. The cyanovinylene counterparts emitted weakly in solution (fl < 2%). Their luminogenic property was demonstrated with a ca. 15-fold increase in emission in the solid state. A 6-fold emission enhancement was also found when they were aggregated in a 90 vol% methanol/water mixture. The solid-state emission enhancement of the cyanovinylene benzofurans was in part attributable to intermolecular contacts that suppressed excited-state deactivation by molecular motion.

An efficient synthesis of a novel series of twelve substituted 2-amino-3-cyano-4H-pyran derivatives was achieved by a one-pot three-component cyclocondensation reaction of heteroaryl aldehydes, malononitrile and active methylene compounds catalyzed by iodine in aqueous medium under ultrasound irradiation. In comparison with conventional methods, our protocol is convenient and offers several advantages, such as shorter reaction time, higher yields, milder conditions and environmental friendliness. We have herein successfully demonstrated the synergistic outcome of multi-component reaction (MCR) and sonication to offer a facile route for the design of these derivatives.
