A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

The volatile fraction of hazelnuts encrypts information about: cultivar/geographical origin, post-harvest treatments, oxidative stability and sensory quality. However, sensory features could be buried under other dominant chemical signatures posing challenges to an effective classification based on pleasant/unpleasant notes. Here a novel workflow that combines Untargeted and Targeted (UT) fingerprinting on comprehensive two-dimensional gas-chromatographic patterns is developed to discriminate spoiled hazelnuts from those of acceptable quality. By flash-profiling, six hazelnut classes are defined: Mould, Mould-rancid-solvent, Rancid, Rancid -stale, Rancid -solvent, and Uncoded KO. Chromatographic fingerprinting on composite 2D chromatograms from samples belonging to the same class (i.e., composite class-images) enabled effective selection of chemical markers: (a) octanoic acid that guides the sensory classification being positively correlated to mould; (b) gamma-nonalactone, gamma-hexalactone, acetone, and 1-nonanol that are decisive to classify OK and rancid samples; (c) heptanoic and hexanoic acids and gamma-octalactone present in high relative abundance in rancid-solvent and rancid-stale samples.

We report on the tetraethylphosphorodiamidate (-OP(O)(NEt2)(2)) group as an effective directed metalation group (DMG). Lithiation-electrophile quench of 1 provides a general synthesis of ortho-substituted aryl and naphthyl phosphorodiamidates 4-8. We also describe the phospha anionic ortho-Fries (AoF) rearrangement of the phosphorodiamidates 1a,1b -> 2 or 3 and its vinylogous counterpart to the ortho-tolyl phosphorodiamidates 5b -> 13. Intermolecular competition experiments demonstrate the approximately equal DMG strength of the -OP(O)(NEt2)(2) and the most powerful OCONEt2 groups.

Recommanded Product: 4-Methoxybenzaldehyde. Recently I am researching about SOLID-PHASE MICROEXTRACTION; VOLATILE COMPOUNDS; HS-SPME; MEAT FLAVOR; FRESH; RAW; MULTIVARIATE; OXIDATION; PORK, Saw an article supported by the Key R&D Program of Ningxia Hui Autonomous Region [2017BY068].

The aroma components of cooked beef meatball stored for different times (0, 30, 60, and 90 days) were analyzed by solid-phase microextraction (SPME) and solvent-assisted flavor evaporation (SAFE) combined with gas chromatography-olfactometry-mass spectrometry (GC-O-MS). Sensory evaluation, odor activity value (OAV), and aroma dilution analysis were used to analyze the variation of volatile flavor substances. A total of 80 volatile compounds was identified in cooked beef balls during storage by SPME, 32 of which were aroma-active; while 42 were identified by SAFE, 15 were aroma-active. Only when the two extraction methods are combined a comprehensive analysis be conducted. The sensory evaluation results show that the overall aroma profile began to weaken and the overall acceptability gradually decreased during storage. It was found that hexanal, 1-octene-3-ol, linalool, 2-ethyl hexyl acetate, diallyl disulfide, eugenol, alpha-pinene, and anisole were the key aroma components of cooked beef meatballs during storage. Practical applications Beef meatball is a spherical food made by adding various spices and ingredients to minced beef together. It is rich in flavor, red in color, and tender in taste, but the study on the volatile compounds of beef meatball aroma is less. By comprehensive flavor analysis of gas chromatography-olfactometry-mass spectrometry (GC-O-MS) with sensory evaluation, it was found that hexanal, 1-octene-3-ol, linalool, 2-ethyl hexyl acetate, diallyl disulfide, eugenol, alpha-pinene, and anisole were the key aroma components of cooked beef meatballs during storage. And during the storage of cooked beef ball, its overall aroma began to weaken and the overall acceptability gradually decreased. So by adding natural antioxidant substances and shortening the storage period, the flavor quality of cooked beef ball could be controlled and improved.

Benzodiazepines (BZDs) have been widely used in neurological disorders such as insomnia, anxiety, and epilepsy. The use of classical BZDs, e.g., diazepam, has been limited due to adverse effects such as interaction with alcohol, ataxia, amnesia, psychological and physical dependence, and tolerance. In the quest for new benzodiazepine agonists with more selectivity and low adverse effects, novel derivatives of 4,6-diphenylpyrimidin-2-ol were designed, synthesized, and evaluated. In this series, compound 2, 4-(2-(benzyloxy)phenyl)-6-(4-fluorophenyl) pyrimidin-2-ol, was the most potent analogue in radioligand binding assay with an IC50 value of 19 nM compared to zolpidem (IC50 = 48 nM), a nonbenzodiazepine central BZD receptor (CBR) agonist. Some compounds with a variety of affinities in radioligand receptor binding assay were selected for in vivo evaluations. Compound 3 (IC50 = 25 nM), which possessed chlorine instead of fluorine in position 4 of the phenyl ring, exhibited an excellent ED50 value in most in vivo tests. Proper sedative-hypnotic effects, potent anticonvulsant activity, appropriate antianxiety effect, and no memory impairment probably served compound 3, a desirable candidate as a benzodiazepine agonist. The pharmacological effects of compound 3 were antagonized by flumazenil, a selective BZD receptor antagonist, confirming the BZD receptors? involvement in the biological effects of the novel ligand.

The highly enantioselective synthesis of p-anisoin was achieved via the benzoin condensation of a prochiral p-anisaldehyde using achiral NHC catalysts such as vitamin B1. In this reaction, p-anisoin crystallized as a conglomerate, and the deracemization of racemic p-anisoin under basic conditions was efficiently performed by Viedma ripening. Although the handedness of the enantioselective crystallization could not be controlled by spontaneous crystallization, it could be controlled by the coexistence of a catalytic amount of optically active valine. It was clarified that this is due to the asymmetric transformation of p-anisoin with enantiomeric valine in the mother liquor.

DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

The amide C-N cleavage has drawn a broad interest in synthetic chemistry, biological process and pharmaceutical industry. Transition-metal, luxury ligand or excess base were always vital to the transformation. Here, we developed a transition-metal-free hydrogen-bond-assisted esterification of amides with only catalytic amount of base. The proposed crucial role of hydrogen bonding for assisting esterification was supported by control experiments, density functional theory (DFT) calculations and kinetic studies. Besides broad substrate scopes and excellent functional groups tolerance, this base-catalyzed protocol complements the conventional transition-metal-catalyzed esterification of amides and provides a new pathway to catalytic cleavage of amide C-N bonds for organic synthesis and pharmaceutical industry.
