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, Organic Letters called Modular Synthesis of Highly Substituted Pyridines via Enolate α-Alkenylation, Author is Hardegger, Leo A.; Habegger, Jacqueline; Donohoe, Timothy J., which mentions a compound: 3194-15-8, SMILESS is O=C(C1=CC=CO1)CC, Molecular C7H8O2, SDS of cas: 3194-15-8.

A novel methodol. for the synthesis of highly substituted pyridines e. g., I, based on the palladium-catalyzed enolate α-alkenylation of ketones is presented; the formation of aromatic compounds is a new direction for this catalytic C-C bond forming reaction. In the key step, a protected β-haloalkenylaldehyde participates in α-alkenylation with a ketone to afford a 1,5-dicarbonyl surrogate, which then undergoes cyclization/double elimination to the corresponding pyridine product, all in one pot. The β-haloalkenylaldehyde starting materials can be obtained from the corresponding methylene ketone via Vilsmeier haloformylation. Using this concise route, a variety of highly substituted pyridines were synthesized in three steps from com. available compounds

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic.

Mixtures of glycine, glucose, and starch were extrusion cooked using sodium hydroxide at 0, 3, and 6 g/L of extruder water feed, 18% moisture, and 120, 150, and 180 °C target die temperatures, giving extrudates with pH values of 5.6, 6.8, and 7.4. Freeze-dried equimolar solutions of glucose and glycine were heated either dry or after equilibration to ∼13% moisture at 180°C in a reaction-tube system designed to mimic the heating profile in an extruder. Volatile compounds were isolated onto Tenax and analyzed by gas chromatog.-mass spectrometry. For the extrudates, total yields of volatiles increased with decreasing pH at 180°C, reached a maximum at pH 6.8 at 150°C, and increased with increasing pH at 120°C. Amounts increased with temperature at all pH values. Pyrazines were the most abundant class for all sets of conditions (54-79% of total volatiles). Pyrroles, ketones, furans, oxazoles, and pyridines were also identified. Yields of volatiles from the reaction-tube samples increased by >60% in the moist system. Levels of individual classes also increased in the presence of moisture, except pyrazines, which decreased ∼3.5-fold. Twenty-one of the compounds were common to the reaction-tube samples and the extrudates.

A series of 2-[[(2-alkoxy-6-pentadecylphenyl)methyl]thio]-1H-benzimidazoles, benzothiazoles and benzoxazoles have been prepared from anacardic acid and their ability to inhibit human cyclooxygenase-2 enzyme (COX-2) investigated. The active compounds were screened for cyclooxygenase-1 (COX-1) inhibition.

Exchange kinetics between the rotamers of 2-acylfurans and -thiophenes, the main research direction is rotation barrier acylfuran acylthiophene; acylfuran rotation barrier NMR; acylthiophene rotation barrier NMR; conformation acylfuran acylthiophene NMR; furan acyl conformation NMR; thiophene acyl conformation NMR.Recommanded Product: 1-(Furan-2-yl)propan-1-one.

Low-temperature 13C NMR spectra showed 2 different groups of signals, corresponding to the O,O-anti- and O,O-syn-rotamers, of 2-acylfurans I (X = O; R = H, Me, Et, CHMe2, CHEt2, CMe3). The ratios of these rotamers in Me2O were obtained; barriers for the syn-anti interconversion decrease with the increasing bulkiness of R. Although sep. 13C signals could not be detected for the rotamers of the corresponding 2-acylthiophenes I; (X = S, R = as before), line-broadening effects nonetheless allowed measurement of the interconversion barriers. Lanthanide-induced shift experiments carried out on the latter derivatives (at both 1H and 13C frequencies) showed that in all the 2-acylthiophenes investigated, the S,O-syn rotamers are predominant.

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.

The magnetic nanoparticles-supported tungstosilicic acid (TSAMNP) was found to be a highly efficient solid acid for the synthesis of benzoazoles in water. TSAMNP catalyst was achieved by the immobilization of tungstosilicic acid [H4(W12SiO40)] species on the silica core-shell magnetic nanoparticles (Fe3O4@SiO2). A variety of aldehydes were successfully condensed with 1,2-diaminobenzene, 2-aminophenol and 2-aminothiophenol in water as a green solvent to synthesize benzoazoles in good-to-excellent yields. TSAMNP catalyst was easily separated from the reaction mixture and reused several times without any loss of efficiency.
