Attempted nucleophilic displacements of L-rhamnosyl 2,4-bistriflates led to serendipitous formation of a chiral diene via competing cascade eliminations. The reaction also followed the same pathway with D-rhamnosyl and Dmannosyl 2,4-bistriflates substrates providing access to dienes with opposite stereochemistry. The reaction presumably proceeds through E2 elimination of C2 triflate followed by allylic rearrangement. The easily accessible chiral dienes would be useful in the synthesis of natural products.

Herein, we report a simple and efficient approach to synthesize a functionalized 2,18-dimethoxy-5,10,15-trioxa[9]helicene. It was synthesized from simple phenol building blocks using two subsequent reactions namely oxidative coupling and dehydrative cyclization or palladium mediated cyclization. The molecular integrity of the helical core was determined by single-crystal X-ray diffraction and NMR techniques. Its crystal structure showed the spontaneous resolution which was attributed to the conglomerate formation of the same helical isomer via C-H…O and pi…pi or H…pi interactions. Then, it was converted to racemic 2,18-dihydoxy-5,10,15-trioxa[9]helicene. Enantiomers were separated on preparative HPLC with high optical purity (>99 % ee). Based on electronic circular dichroism, the absolute configurations of dextrorotary and levorotatory antipodes were assigned as P and M, respectively. We also studied the absorption, emission and chiroptical behavior of these helical compounds in the solution state.

Outfitting an aza-crown ether with an organotransition-metal pendant provides a mechanism for tuning its supramolecular properties. The binding affinity can be tuned by more than 2 orders of magnitude by changing the identity of the transition metal-center, altering the overall charge of the complex, or engaging in organometallic ligand substitution reactions. High Li+ selectivity (up to 29-fold higher affinity in comparison to Na+), proton-responsive behavior, and ion pair (ditopic) binding capabilities are observed in the metallacrown ethers.

In the treatment of wastewaters contaminated with phenol and substituted phenols, an intermediate chemical step of partial oxidation is often employed to facilitate the ensuing biodegradation process. Ozonation is a candidate technique for partial oxidation of phenolics. In this study, the kinetics of ozonation reactions of 20 substituted phenols is investigated using the renowned theory of mass transfer with chemical reaction. The stirred (Lewis) cell with a flat interface is used as a model contactor. It is found that the second-order rate constants for the reactions with the chosen phenolic compounds are in the 10(4)-10(7) s(-1) range. In particular, the rate constant for ozonation of phenol is 5.06 x 10(6) M-1 s(-1). The liquid-side mass transfer coefficient is estimated by using the chemical method, and its value (k(L) = 0.052 cm s(-1)) is in line with those typical of stirred-cell reactors. This work is useful for the design, operation, and scale-up of ozonation reactors used in wastewater treatment.

This work discusses a new measurement concept that uses contactless Raman spectrometry of free radical polymerization (FRP) in a milliscale reactor. The setup is based on a multiphase system with unsteady operation due to a change in the flow direction. The objective is to develop a quasi-isothermal measurement method for the determination of reaction kinetics with high automation capability. The FRP of acrylic acid with 2,2′-azobis(2-methylpropionamidine) dihydrochloride as the initiator serves as the model reaction. The reaction order for the initiator and monomer concentrations as well as the temperature dependence is determined. On the basis of the measured rates, an estimation of the thermal behavior of the reactor can be made. The pendular slug reactor is an extension of the known measurement methods for FRP and requires only a few grams of material.

The fluoroalkylation of various nucleophilic reagents with (phenylsulfonyl)difluoromethyl (PhSO2CF2)-substituted phenanthridines was achieved to give fluorinated phenanthridine derivatives, which enables the construction of both carbon-heteroatom and carbon-carbon bonds via the substitution of the phenylsulfonyl group. Mechanistic studies indicated that these reactions proceed through a unimolecular radical nucleophilic substitution (S(RN)1) mechanism. It is worthwhile noting that in the cases of O-nucleophiles (t-BuO- and PhO-), the addition of t-BuOK/PhCHO could significantly promote the reactions, due to the in situ formation of a highly reactive electron donor species through the interaction of t-BuOK, PhCHO, and the solvent DMF, which can effectively initiate the single electron transfer process.

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.

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.
