A three-component cascade reaction for the synthesis of 1,3,4-selenadiazoles and their derivatives from arylaldehydes, hydrazine, and elemental selenium by using molecular iodine is reported. This strategy is operationally simple, well-suited to a wide range of functional groups, and provides the desired products in moderate to excellent yields. The proposed mechanism predicts that the reaction tolerated a radical process.

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.

Recently I am researching about NONCANONICAL POLY(A) POLYMERASE; POLYADENYLATION SIGNAL; MOLECULAR-BIOLOGY; STEM-LOOP; VIRUS; DEGRADATION; EXOSOME; TRAMP; DECAY; TRANSCRIPTS, Saw an article supported by the Hepatitis B Foundation; Commonwealth of Pennsylvania.

Through research, I have a further understanding and discovery of 4-Hydroxyquinolin-2(1H)-one. Formula: C9H7NO2

Inhibition of the host RNA polyadenylating polymerases, PAPD5 and PAPD7 (PAPD5/7), with dihydroquinolizinone, a small orally available, molecule, results in a rapid and selective degradation of hepatitis B virus (HBV) RNA, and hence reduction in the amounts of viral gene products. DHQ, is a first in class investigational agent and could represent an entirely new category of HBV antivirals. PAPD5 and PAPD7 are noncanonical, cell specified, polyadenylating polymerases, also called terminal nucleotidyl transferases 4B and 4A (TENT4B/A), respectively. They are involved in the degradation of poor-quality cell transcripts, mostly noncoding RNAs and in the maturation of a sub-set of transcripts. They also appear to play a role in shielding some mRNA from degradation. The results of studies with DHQ, along with other recent findings, provide evidence that repression of the PAPD5/7 arm of the cell RNA quality control pathway, causes a profound (multifold) reduction rather than increase, in the amount of HBV pre-genomic, pre-core and HBsAg mRNA levels in tissue culture and animal models, as well. In this review we will briefly discuss the need for new HBV therapeutics and provide background about HBV transcription. We also discuss cellular degradation of host transcripts, as it relates to a new family of anti-HBV drugs that interfere with these processes. Finally, since HBV mRNA maturation appears to be selectively sensitive to PAPD5/7 inhibition in hepatocytes, we discuss the possibility of targeting host RNA quality control as an antiviral strategy.

A clean and effective method has been developed for the regioselective of O-allylation of phenol derivatives using a recyclable Cu(I)-exchanged multi-size porous material. Ease of preparation of catalyst through simple solid-state exchange and its compatibility in producing excellent amount of O-allylated products and a plausible mechanistic pathway for the regioselectivity are highlighted. This reported procedure is not requiring any external stabilizing ligand for Cu(I) species and further purification of products.

A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic alcohols or amines with the reaction showing excellent functional group tolerance.

A copper-catalysed hydroxylation of diaryliodoniums to generate phenols and diaryl ethers is reported. This method allows the synthesis of diversely functionalized phenols under mild reaction conditions without the need for a strong inorganic base or an expensive noble-metal catalyst. Significantly, convenient application of diaryliodoniums is demonstrated in the preparation of diaryl ethers in a one-pot operation.

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] .

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.

A cobalt-complex-catalyzed borylation of a wide range of alkyl halides with a diboron reagent (B(2)pin(2) or B(2 )neop(2)) has been developed under mild reaction conditions, demonstrating the first cobalt-mediated cross-coupling with alkyl electrophiles. This protocol allows alkyl boronic esters to be accessed from alkyl halides, including alkyl chlorides, which were used rarely as coupling partners. Mechanistic studies reveal the possible involvement of an alkyl radical intermediate in this cobalt-mediated catalytic cycle.
