Industrial-scale synthesis of eldecalcitol is described. AA highly diastereoselective epoxidation of p-methoxybenzyl (PMB) protected dienol at room temperature provides the key epoxide intermediate with a secondary hydroxyl group, which is alkylated with a triflate to set up all of the subunits at the C-1, C-2, and C-3 positions of the A-ring fragment. Selective protecting group manipulation followed by palladium-catalyzed cyclization then provides the A-ring synthon. The C/D-ring fragment is obtained by (1) direct C-H hydroxylation of Grundman’s ketone using in situ prepared trifluoropropanone dioxirane and (2) protection. Finally, the coupling of the A-ring with the C/D-ring fragment, global deprotection, and recrystallization provide the highly crystalline eldecalcitol.

1,2,3-Triazole contained conjugated porous polymers (CPPs) have recently emerged as a new class of efficient photocatalysts. To gain more insight into the excellent photocatalytic activity of this kind of CPPs, herein, we report the design and preparation of a series of 1,2,3-triazole-based CPPs via oxidative coupling polymerization to study their photocatalytic performance. These CPPs have donor-acceptor properties and 1,2,3-triazole serves as an electron acceptor. The resulting CPPs with thiophene, carbazole and diphenylamine as electron donor units, respectively, have distinct porosities and optoelectronic properties, and showed effective photocatalytic performance towards oxidative hydroxylation of arylboric acids and alkylation of vinylarenes with diethyl bromomalonate or bromoacetonitrile. The thiophene contained CPP was a more efficient photocatalyst for the catalytic reactions, which can be attributed to its smaller optical band gap and greater charge separation effi-ciency. Furthermore, PTPT has shown reliable recyclability with no significant loss in its catalytic activity.

In the current research, much attention is paid to heterogenized nanostructure. Herein, we report the green synthesis magnetic nanoparticles (MNPs) of cobalt ferrite by the immobilization of erbium (Er) coated with folic acid (FA) which show effective catalytic properties and recyclability. Full characterizations with field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray atomic mapping, thermal gravimetric analysis (TGA), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), inductively coupled plasma-optical emission spectrometry (ICP-OES), and Fourier-transform infrared (FT-IR) spectroscopy techniques were undertaken to uncover structural properties of the prepared magnetic catalyst. The obtained nanohybrid complexes as efficient, recyclable, and green heterogeneous systems pave the way for producing pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2-c]chromenes derivatives by the one-pot three-component condensation reaction of various aldehydes, malononitrile, and hydroxycoumarin or barbituric acid in green condition. This easily prepared organometalic catalyst presents many superiorities such as operational simplicity, high yield, short reaction time, utilization of commercially available or easily accessible starting materials, eco-friendly properties, and excellent purity. Most importantly, erbium-FA-coated CoFe2O4 can be easily separated and recycled from the reaction system using an external magnetic field. The magnetically recoverable biocatalyst can be recycled and reused six times while maintaining high activities. The activity of the magnetic catalyst can be maintained at more than 80% of that of the previous cycle. This research solves the recovery problem encountered in industrial applications of biocatalysts and presents a clean and green method for preparing pyrimidinones and chromenes.

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.

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.
