Author is Melhado, Asa D.; Luparia, Marco; Toste, F. Dean.

The catalytic enantioselective 1,3-dipolar cycloaddition of munchnone dipoles with electron-deficient alkenes is described. The reaction is catalyzed by chiral bis(phosphine)gold(I) benzoate complexes and provides Δ1-pyrrolines, e.g., I, with excellent regio-, diastereo-, and enantioselectivity. The reaction is proposed to proceed through a 1,3-dipole generated by deprotonation of a gold(I)-activated azlactone.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Synthesis and characterization of amino glucose-functionalized silica-coated NiFe2O4 nanoparticles: A heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of 2,4,5-trisubstituted imidazoles, benzo[d]imidazoles, benzo[d] oxazoles and azo-linked benzo[d]oxazoles.SDS of cas: 6797-13-3.

Amino glucose-functionalized silica-coated NiFe2O4 nanoparticles (NiFe2O4@SiO2@amino glucose) were chem. synthesized and characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), thermal gravimetric anal. (TGA), energy dispersive X-ray anal. (EDX), vibrating sample magnetometer (VSM), Zetasizer and Fourier transform IR spectroscopy (FT-IR) instruments. NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of 2,4,5-trisubstituted imidazoles through one-pot multicomponent condensation of benzil or benzoin, ammonium acetate with aryl aldehydes and for the synthesis of benzoxazoles using condensation reaction of 2-aminophenol with aryl aldehydes under solvent free condition. In the other study, this synthesized magnetically reusable catalyst was introduced as a new avenue for the synthesis of benzo[d]imidazoles using the reaction between aryl aldehydes and 1,2-diaminobenzene. These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for five cycles with almost consistent activity. Synthesized compounds were characterized by their phys. constant, comparison with authentic samples, FT-IR, 1H NMR, 13C NMR spectroscopy and elemental anal.

COA of Formula: C9H9NO. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Biomimetic Synthesis of Benzimidazoles, Benzoxazoles and Benzothiazole via the Group Transfer of Tetrahydrofolate Models. Author is Wen, Xueshan; Chen, Jianxin; Zhao, Yanqin; Chang, Xingmao; Ma, Jiachun; Zheng, Wenjun.

2-Substituted benzimidazoles, benzoxazoles I [R = Et, n-Pr, i-Pr, etc.; X = NH,O], and 2-cyclohexylbenzothiazole were prepared in good yields by biomimetic reaction of o-phenylenediamine/o-aminophenol/o-aminothiophenol with imidazolium iodides as tetrahydrofolate model compounds at the oxidation level of formate. The reaction probably involved nucleophilic addition to the C=N bond at the imidazolium ring followed a 1,3-H migration at imidazolidine intermediate and a salt elimination. This biomimetic synthesis method offers advantages such as good yields of products, easy work-up, mild reaction conditions without the use of oxidants, acid, catalyst or microwave irradiation

Category: benzoxazole. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Mercapto-5-methylbenzimidazole, is researched, Molecular C8H8N2S, CAS is 27231-36-3, about Electrochemical study of 2-mercaptoimidazole as a novel corrosion inhibitor for steels. Author is Alvarez-Bustamante, R.; Negron-Silva, G.; Abreu-Quijano, M.; Herrera-Hernandez, H.; Romero-Romo, M.; Cuan, A.; Palomar-Pardave, M..

From electrochem. methods, polarization resistance and electrochem. impedance spectroscopy, the corrosion susceptibility of pipeline steel samples immersed in 1 M H2SO4 was determined using nil and different concentrations of the mol. 2-mercaptoimidazole (2MI). A corrosion inhibiting efficiency, IE, value of 98.5% was reached when the 2MI concentration in the system increased to 25 ppm. Also, at this concentration, the 2MI IE was measured as a function of time finding that the IE kinetics follows the relation: %IE = 98.5-0.03t after 800 h of evaluation. During the 1st 200 h 2MI IE was higher that 90% then, it decreased to 70% and it remained constant up to 1200 h. This compound can affect both the anodic and cathodic processes, thus it can be classified as a mixed-type inhibitor however, from variation of both corrosion potential and polarization resistance with [2MI] it was possible to state that the anodic reaction rate, of the corrosion process, decreases at a greater proportion than the cathodic one. 2MI follows an adsorption mechanism, which can be adequately described by the Langmuir isotherm with an adsorption standard free energy difference (ΔG°ads) of -26.8 kJ mol-1. To analyze the influence of substituting groups, both electron-donating and electron-attracting and the number of π-electrons on the corrosion inhibiting properties of organic mols., an electrochem. study was carried out on four different mols. having similar chem. framework structure: 2-mercaptoimidazole (2MI), 2-mercaptobenzoimidazole (2MBI) 2-mercapto-5-methylbenzimidazole (2M5MBI) and 2-mercapto-5-nitrobenzimidazole (2M5NBI). The IE order followed by the mols. tested was 2MI > 2MBI > 2M5MBI > 2M5NBI. Thus 2MI turned out to be the best inhibitor, even superior to the 2MBI. This fact strongly suggests that, contrary to a hitherto generally suggested notion, an efficient corrosion inhibiting mol. does not require to be a large one, also bearing an extensive number of π-electrons.

In addition, there is a lot of other information about this compound (cas:503538-69-0) here.

The enantioselectivity of a Pd-catalyzed domino Heck-Mizoroki cyclization is dramatically enhanced by ligand and solvent choice. Electron-deficient ligands such as (R)-DIFLUORPHOS gave I in %ee values ranging from 94% ee to >99% ee. EtOH was found to be superior to other solvents traditionally used in Heck-Mizoroki reactions, generally showing increases in enantioselectivity when compared to toluene. It is also shown that microwave heating accelerates the reaction in either solvent and allows for a longer catalyst lifetime without eroding the %ee.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Food Chemistry called Accelerating aroma formation of raw soy sauce using low intensity sonication, Author is Gao, Xianli; Liu, Ermeng; Zhang, Junke; Yang, Lixin; Huang, Qingrong; Chen, Sui; Ma, Haile; Ho, Chi-Tang; Liao, Lan, which mentions a compound: 3194-15-8, SMILESS is O=C(C1=CC=CO1)CC, Molecular C7H8O2, Computed Properties of C7H8O2.

Sonication was applied to accelerate aroma formation and shorten fermentation time of soy sauce. Effects of sonication at 68 kHz on the aroma and aroma-producing Zygosaccharomyces rouxii and Tetragenococcus halophilus in moromis were investigated using sensory evaluation, SPME-GC-olfactometry/MS, viable cell counting and SEM. The sensory scores of caramel-like, fruity, alc., floral, malty, smoky, sour and overall aroma in sonicated moromis were enhanced by 23.4%, 23.2%, 13.6%, 12.8%, 7.6%, 6.3%, 5.6% and 14.4%, resp. Sensory scores of samples fermented for 90-180 days were higher than those of controls fermented for 180 days, suggesting that sonication could reduce fermentation time by 90 days. Thirty-four aroma-active compounds were detected from 85 volatile compounds in soy sauces. Sonication accelerated and elevated the formation of aroma compounds by chem. reactions. It also markedly increased the reproduction and cell permeability of both microorganisms in moromis, which favored the formation of aroma compounds by both strains.
