A facile and efficient method for the preparation of 3-imidazolylpropionic acid N-oxides has been developed. It involves condensation of 2-unsubstituted imidazole N-oxide with an aldehyde and Meldrum’s acid followed by hydrolysis and decarboxylation of the corresponding adduct. This method tolerates a broad variation in the structure of starting aldehydes as well as N-oxides.

This work aims to encapsulate anthocyanins and phenolic compounds extracted from a native Brazilian fruit peel – jabuticaba (Plinia cauliflora (Mart.) Kausel) and propolis from Tubuna (Scaptotrigona bipunctata) stingless bees, with great potential benefits for human health. The alginate encapsulation was conducted by the ionotropic gelation through the dripping into the CaCl2 solution. Both raw extracts were characterized by TPC – total phenolic content (Folin-Ciocalteu), AA-antioxidant activity (DPPH and ABTS assays), and TMAC – total monomeric anthocyanin concentration (pH differential method); as well as their resultant mixture (2:1 jabuticaba/propolis). The obtained beads presented highly efficient encapsulation of total polyphenols (similar to 98%) and monomeric anthocyanins (similar to 89%), with spherical morphology and smooth surface obtaining a mean diameter between 200 and 250 mu m. In vitro release study showed that JPE/alginate beads were completely disintegrated at pH 7.4 (intestinal pH), but they were resistant to gastric pH (1.2) presenting a slow release of about 40% in 240min. This is the first report that encapsulates the mixture of jabuticaba and propolis extracts and may contribute to the utilization of a great source of bioactive compounds besides the potential pigment of anthocyanins, an alternative to natural and healthy food/beverage colorants.

Electro-synthesis through a one-pot three-component condensation of corresponding aldehydes, Meldrum’s acid, and 2-(nitromethylene)imidazolidine resulted in a series of novel tetrahydroimidazo[1,2-a]pyridine-5(1H)-one derivatives containing an electronegative pharmacophore (=CNO2). The process was carried out in propanol medium with sodium bromide presented as electrolyte, inside an undivided cell with good to excellent yields. As a powerful entry into fused polycyclic structures related to bioactive heterocycles, this green protocol shows great potential. [GRAPHICS] .

The reactions of the trihydride niobocene complex [NbCp’H-2(3)] (Cp’ = eta(5)-C5H4SiMe3) (1) with different alpha,beta-unsaturated carboxylic acids have been studied. The reactions with fumaric and maleic acids (A and B) gave a new dinuclear carboxylato-containing niobocene derivative [(NbCp'(2))(2)(mu-kappa O-2,O-OOC-CH2-CH2-COO-kappa O-2,O)] (2), due to the occurrence of two processes, dihydrogen elimination and hydrogenation of the C=C bond of the alpha,beta-unsaturated carboxylic acid. Likewise, the use of an alpha,beta-unsaturated carboxylic acid derivative such as mono-methyl fumarate (ester) (C) gave the mononuclear [NbCp'(2)(OOC-CH2-CH2-COOMe-kappa O-2,O)] (3). When other alpha,beta-unsaturated carboxylic acids with less activated alkenes were used, such as trans-cinnamic acid (F), (E)-2-methyl-3-phenylacrylic acid (G), cyclohex-1-ene-1-carboxylic acid (H), 3-methylbut-2-enoic acid (I), (E)-2-methylbut-2-enoic acid (J) or (E)-pent-2-enoic acid (K), only the complexes [NbCp'(2)(OOCR-kappa O-2,O)], (R = trans-CH = CHPh (4), trans-CMe = CHPh (5), 1-cyclohexenyl (6), (CH = CMe2) (7), (cis-CMe = CHMe) (8), (trans-C(H) = CH-Et) (9)), were isolated, respectively, resulting from a process with dihydrogen elimination and the hydrogenation of the C=C bond do not takes place. Treatment of 2-9 with CO (3 atm) promote that the coordination mode of the carboxylate ligand changes from (kappa O-2,O-OOC-R) to (kappa O-1-OOC-R) and yielding new carbonyl derivatives [(NbCp'(2))(2)(mu-kappa O-1-OOC-CH2-CH2-COO-kappa O-1) (CO)(2)] (10); and [NbCp'(2)(OOCR-kappa O-1) (CO)] (R = CH2-CH2-COOMe (11), trans-CH = CHPh (12), trans-CMe = CHPh (13), 1-cyclohexenyl (14), CH = CMe2 (15), cis-CMe = CHMe (16) and R = trans-CH] CH-Et) (17)). Reaction of 2 with O-2 afford a new diperoxo compound [{NbCp'(2)(O-2-kappa O-2,O)}(2) (mu – kappa O-1-OOC-CH2-CH2-COO-kappa O-1)] (19), through a monoperoxo derivative [NbCp'(2)(O-2-kappa O-2,O) (mu-kappa O-1-OOC-CH2-CH2-COO-kappa O-2,O) NbCp'(2)] (18). All the new complexes were characterized by usual IR and NMR spectroscopic methods and the crystal structure of 16 and 18 were determined by X-ray diffraction studies. (c) 2019 Elsevier B.V.

We disclosed an efficient Pd-catalyzed domino reaction for facile synthesis of spirooxindoles and [3,4]-fused oxindoles from alkene-tethered carbamoyl chlorides. The five-membered C,C-palladacycle obtained through intramolecular C-H activation should act as the key intermediate in both catalytic cycles. A variety of functionalized spirooxindoles and [3,4]-fused oxindoles were synthesized in moderate to good yields.

This study evaluated the effect of different sugar smoking times on the flavour profiles of chicken drumsticks using an electronic nose (E-nose), electronic tongue (E-tongue), and headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME/GC-MS). The moisture content, water activity, pH, and L*-value decreased from 71.26% to 65.23%, 0.987 to 0.979, 6.66 to 5.36, and 61.84 to 52.34, respectively (P < 0.05). The a*-value and b*-value increased from 4.96 to 9.65 and 16.61 to 26.45, respectively (P < 0.05) with the increase in smoking times. Seventy-five volatile compounds were identified, and 18 volatile compounds were identified as key odour compounds and among them seven key volatile compounds with variable importance in projection (VIP) > 1 were detected. Principal component analysis of E-nose, E-tongue, and HS-SPME/GC-MS indicated that 3-, 4-, and 5-min smoking samples had similar odour and taste profiles. Sensory analysis indicated that the 4-min sample had increased overall acceptability. The correlation analysis of E-nose and key volatile compounds with odour activity value > 1 and VIP >1 confirmed that W1C, W3C, and W5C sensors were sensitive to aromatic compounds, and W2S sensor was sensitive to ketones. These results may provide guidance for smoked chicken producers to reasonably control flavour formation.

Iridium/Bronsted acid cooperative catalyzed asymmetric allylic substitution reactions at the C5 position of indolines have been reported for the first time. The highly efficient protocol allows rapid access to various C5-allylated products in good to high yields (48-97%) and enantioselectivities (82% to >99% ee) with wide functional group tolerance. The transformations allow not only the formation of C5-allylindoline derivatives but also the synthesis of C5-allylindole analogues in good yields and excellent stereoselectivities via an allylation/oxidation reaction sequence.

SDS of cas: 100-51-6, Reprint Addresses Prech, J (corresponding author), Charles Univ Prague, Fac Sci, Dept Phys & Macromol Chem, Albertov 6, Prague 12843 2, Czech Republic.. The CAS is 100-51-6.

Citronellol is one of the most widely used fragrances for bouquetting purposes and it is a starting material for synthesis of several other terpenoids. Nevertheless, few data have been reported on citronellol selective oxidation. Accordingly, we report our findings on the selective oxidation of citronellol with hydrogen peroxide using a set of titanosilicate catalysts with different morphologies and textural properties-conventional titanium silicalite 1 (TS-1), mesoporous TS-1, layered TS-1 and silica-titania pillared TS-1 and also studying the effect of the solvent used. Epoxidation of C6=C7 double bond was the main primary reaction in this system and trace signals of C5 allylic oxidation products were observed without formation of citronellal. Due to the presence of post-synthesis introduced additional Ti sites, the silica-titania pillared TS-1 (TS-1-PITi) provided the highest conversion among the tested catalysts; nevertheless, citronellol was oxidized over all the studied catalysts including conventional TS-1; therefore, showing that it penetrates even into MFI micropores (0.55 nm in diameter). When using acetonitrile as a solvent, the conversion was proportional to the titanium content of the catalyst. When studying the effect of the solvent, acetonitrile provided the highest epoxide selectivity (55%) while in methanol, 2-propanol and 1,4-dioxane, ring opening reactions caused epoxide decomposition.
