An elegant approach was presented for the synthesis of novel alpha-aminophosphonates: a three-component one-pot condensation of 3-(trifluoromethyl)aniline, substituted aromatic aldehydes, and diethyl phosphite using a nickel-based metal-organic framework (Ni-MOF). The Ni-MOF was synthesized using 4,4 ‘-biphenyldicarboxylic acid and further characterized using various techniques such as X-ray diffraction, Fourier-transform infrared, thermogravimetry/differential thermal analysis, Brunauer-Emmett-Teller, and field-emission scanning electron microscopy analyses. Ni-MOF seems to be an eco-friendly, an easily recyclable, and heterogeneous catalyst up to the eighth run with minimal reduction in its catalytic activity. The synthesized alpha-aminophosphonates were also investigated for antibacterial and antioxidant activities. In few cases, compounds 4a-4x show similar as well as higher antibacterial activity. Among the synthesized alpha-aminophosphonates, 4a-4x had more potent antibacterial activity against pathogenic bacteria while compounds 4h, 4m, 4n, 4q, 4u, 4v, and 4w exhibited significant antioxidant activity.

Cyperus esculentus tubers are the raw material to prepare tigernut milk (horchata), which can be marketed under Protected Designation of Origin (PDO) C hufa de Valencia. The aim of this study was to characterize commercial tigernut milks and compare PDO and non-PDO products. The following aspects were studied: (i) volatile profile, (ii) descriptive sensory profile, (iii) consumer satisfaction degree. The key volatile compounds were limonene, benzaldehyde, linalool and m-methoxyanisole. Principal component analysis indicated a mix of PDO and nonPDO samples in the groups formed. The highest consumer satisfactions were observed for 2 PDO samples. Penalty analysis showed that 80% of non-PDO samples needed improvements, while this percentage drastically decreased to 40% for PDO samples. The online study proved that a lot of people drink horchata, less people know the PDO Chufa de Valencia and even less people consume the protected product consciously. In conclusion, there was not a clear difference among protected and non-protected tigernut milks respect to volatile compounds but there were differences in the degree of consumer preference. So, it is clear that a lack of knowledge regarding the product and its PDO exists and needs attention.

I found the field of Chemistry; Crystallography very interesting. Saw the article Systematic investigation of hydrogen-bond propensities for informing co-crystal design and assembly published in 2019.

Co-crystallizations can be utilized for generating new solid forms of a target substance in order to alter or enhance some specific bulk physical property. Generally, selection of the co-former (the necessary partner for the target molecule) is based on existing structural information about molecular recognition events involving complementary functional groups, and extensive experimental screening methods. In this study, we utilize structure-informatics in an attempt to predict if two different molecules will form a co-crystal or not. Our study is based on hydrogen-bond propensity (HBP), and the key premise of our approach rests on whether target-co-former interactions are more likely to take place than either target-target or co-formerco-former hydrogen bonds. We examined six different target molecules in combination with 25 possible co-formers each and used the HBP protocol for predicting if a co-crystal would form or not. The predictions were then compared with results from an experimental co-crystal screen of the 150 different combinations. The correct outcome was successfully predicted 92-95% of the time which shows that for this series of small molecules, HBP is a very reliable indicator for determining if a co-crystal will form between a target molecule and a particular co-former.

New RNA modifications are needed to advance our toolbox for targeted manipulation of RNA. In particular, the development of high-performance reporter groups facilitating spectroscopic analysis of RNA structure and dynamics, and of RNA-ligand interactions has attracted considerable interest. To this end, fluorine labeling in conjunction with F-19-NMR spectroscopy has emerged as a powerful strategy. Appropriate probes for RNA previously focused on single fluorine atoms attached to the 5-position of pyrimidine nucleobases or at the ribose 2 ‘-position. To increase NMR sensitivity, trifluoromethyl labeling approaches have been developed, with the ribose 2 ‘-SCF3 modification being the most prominent one. A major drawback of the 2 ‘-SCF3 group, however, is its strong impact on RNA base pairing stability. Interestingly, RNA containing the structurally related 2 ‘-OCF3 modification has not yet been reported. Therefore, we set out to overcome the synthetic challenges toward 2 ‘-OCF3 labeled RNA and to investigate the impact of this modification. We present the syntheses of 2 ‘-OCF3 adenosine and cytidine phosphoramidites and their incorporation into oligoribonucleotides by solid-phase synthesis. Importantly, it turns out that the 2 ‘-OCF3 group has only a slight destabilizing effect when located in double helical regions which is consistent with the preferential C3 ‘-endo conformation of the 2 ‘-OCF3 ribose as reflected in the (3)J (H1 ‘-H2 ‘) coupling constants. Furthermore, we demonstrate the exceptionally high sensitivity of the new label in F-19-NMR analysis of RNA structure equilibria and of RNA-small molecule interactions. The study is complemented by a crystal structure at 0.9 angstrom resolution of a 27 nt hairpin RNA containing a single 2 ‘-OCF3 group that well integrates into the minor groove. The new label carries high potential to outcompete currently applied fluorine labels for nucleic acid NMR spectroscopy because of its significantly advanced performance.

An investigation of the unexpected lability of the Csp(3)-Csp(2)bond connecting 2,4,6-trimethoxyphenyl group and an allylic moiety is carried out. We observed that the catalytic presence of either Lewis or Bronsted acid can render such 2,4,6-trimethoxyphenyl group labile. Several nucleophiles were found to substitute the labile C-C bond in mild reaction conditions resulting in very good yields of the allylated products. Even in the absence of a nucleophile, intramolecular cyclization of the parent substrate under acidic activation caused the labile C-C bond to cleave. A major motivation of this study is to understand the lability of electron-rich aryl group in acidic medium, employing 2,4,6-trimethoxyphenyl moiety as a case study. A plausible mechanism is proposed after carrying out several control reactions as well as UV/Vis and(1)H NMR spectroscopic studies. This work provides an insight into the activation of electron-rich arenes as a labile entity in acidic medium while also adding a conceptually novel C-C bond breaking approach to the vast literature of allylation of arenes.

BACKGROUND: Chemical pesticides are the main measures for pest control, but have caused growing resistance of pests and brought a series of environmental problems. Development of high-efficient insecticidal molecules with novel scaffolds is therefore particularly urgent. RESULTS: Based on a [5 + 1] annulation reaction with 5-amino-1H-phenylpyrazole and dialkyl bromomalonate, 27 novel five-substituted 4,5-dihydropyrazolo[1,5-a]quinazolines were designed following the intermediate derivatization method and synthesized. Bioassay results indicated that most of the test compounds displayed good insecticidal activities against Plutella xylostella, Spodoptera frugiperda, and Solenopsis invicta. In particular, the insecticidal activities of compounds 4a, 4f, and 4m against P. xylostella [median lethal concentration (LC50) values ranged from 3.87 to 5.10 mg L-1] were comparable to that of indoxacarb (LC50 = 4.82 mg L-1). In addition, compounds 4a and 9e showed similar high insecticidal activities against Spodoptera frugiperda (mortality rate = 79.63% and 72.12%) at 100 mg L-1, comparable to that of fipronil (mortality rate: 68.44%); compound 9a showed possible delayed toxicity against Solenopsis invicta (mortality rate: 95.66%) after 5 days of treatment at 1.0 mg L-1. CONCLUSION: Due to their high insecticidal activities against P. xylostella, compound 4m, 4a, and 4f could be considered as qualified candidates for novel insecticide. Several other 4,5-dihydropyrazolo[1,5-a]quinazolines with relatively high bioactivity, such as compounds 9a and 9e, are also worth further optimization as potential insecticide or anticide candidates.

Cellulose benzoate propionates (CBzP) were prepared via a staged addition of Pr2O followed by Bz(2)O to cellulose dissolved in tributylmethylammonium dimethyl phosphate (TBMADMP) providing regioselectively substituted cellulose esters in which the benzoate was preferentially installed at C2 and C3. By systematically varying the DSPr, DSBz, and DSOH (DS = degree of substitution), we synthesized CBzP that could potentially be utilized as a unique compensation film in optical displays.

A new series of novel chromene-based oxadiazole derivatives were synthesized from a variety of chromene-based amidoximes with readily available carboxylic acids under conventional oil bath heating as well as under microwave irradiation. The use of commercially available EDCI and HOBt as coupling reagents in DMF combined with microwave heating resulted in high yields and purities of the product 1,2,4-oxadiazoles in an expeditious manner. This methodology is successfully applied to synthesize 18 numbers of new 2H-chromene-substituted 1,2,4-oxadiazole derivatives in good to high yields. The structure of the product was ascertained by X-ray crystallographic analysis. All the synthesized compounds were evaluated for their in vitro antibacterial activity against two different pathogenic bacterial strains, that is, Escherichia coli (MTCC614) and Klebsiella pneumoniae (MTCC4031). The obtained results from in vitro antimicrobial assays indicated that 6g and 6h exhibited good antibacterial activity nearer to the standard drug, gentamicin. The molecular docking studies showed that compounds 6g and 6h show hydrogen bonding interaction with the bacterial target DNA gyrase of E. coli.
