Electrophilic reactivity of the methoxy-iminium cation (I), resulting from the reaction between dimethyl sulfate and DMF, has been investigated towards electrogenerated carbanions produced by electroreduction of activated polyhalo compounds Controlled potential reduction of di-Et trichloromethylphosphonate (II) in the presence of three equivalent of I in DMF leads to the expected adduct (EtO)₂P(O)CCl₂-CH(NMe₂)OMe (60% yield). Galvanostatic reduction of II in the presence of two equivalent of I leads to mixtures of the enamine (EtO)₂P(O)CCl=CH(NM₂) and the ynamine (EtO)₂P(O)CCNMe₂; when acetic acid is added, a mixture of the enamine and the enol-ether (EtO)₂P(O)CCl=CH(OMe) is obtained. Lastly, the enamine can be synthesized with a 80% yield by electroreducing II in the presence of four equivalent of I in the same way, enamines (MeO₂C)₂C=CH(NMe₂) (40% yield) and (EtO₂C)CCl=CH(NMe₂) (50% yield) are obtained from the electroreduction of di-Me dibromomalonate or Et trichloroacetate, resp.

Kalita, Pranjal published the artcileKIT-5 Supported Copper (II) Oxide Mesoporous Materials: An Efficient Catalyst for Regioselective Synthesis of 1,4- Disubstituted-1H-1,2,3-Triazoles in Water, HPLC of Formula: 620-20-2, the publication is Polycyclic Aromatic Compounds, database is CAplus.

We have synthesized copper-incorporated KIT-5 mesoporous materials which were characterized thoroughly by powder x-ray diffraction, N₂-sorption, UV-Vis, HR-SEM & EDS and HR-TEM techniques. The low angle PXRD with theta values of 0.609, 0.660, 0.704 and 0.746 confirmed the mesoporosity of the synthesized materials. In addition, the materials showed type-IV isotherms which are spherical in morphol. and fringes with pores of materials supporting the formation of mesoporous materials. The catalytic activity of synthesized materials was also investigated. We have used our materials as catalyst for the synthesis of 1,2,3-triazole derivatives via three component reaction of alkyl/aryl halide, terminal alkynes and sodium azide in water as a solvent. The desired triazole products were obtained in very good yields. This study indicates the importance of Cu element, solid support with uniformity of metal nanoparticles over the materials. The recyclability study with PXRD data of the catalyst confirmed the existence of the mesoporosity of the catalyst after the reaction and the yield decreased marginally from 98 to 91% over three cycles. This reaction has broad substrate scope and is compatible for aliphatic, aromatic, allyl substrates giving high yield of triazole products.

An efficient and general catalysis process was developed for the direct preparation of various primary O-thiocarbamates/carbamates as well as monosubstituted thioureas/ureas by using thiourea/urea as biocompatible thiocarbonyl (carbonyl) sources. This procedure used choline chloride/tin(II) chloride [ChCl][SnCl₂]₂ with a dual role as a green catalyst and reaction medium to afford the desired products in moderate to excellent yields. Moreover, the DES can be easily recovered and reused for seven cycles with no significant loss in its activity. Besides, the method shows very good performance for synthesizing the desired products on a large scale.

Herein authors report the catalytic atroposelective syntheses of pharmaceutically relevant 3-arylquinolines via the nucleophilic aromatic substitution (SNAr) of thiophenols into 3-aryl-2-fluoroquinolines mediated by catalytic amounts of Cinchona alkaloid-derived ureas. These reactions displayed a spectrum of dynamic kinetic resolution (DKR) and kinetic resolution (KR) characters depending upon the stereochem. stability of the starting material. Low barrier substrates proceeded via DKR while higher barrier substrates proceeded via KR. On the other hand, substrates with intermediate stabilities displayed hallmarks of both DKR and KR. Finally, authors also show that they can functionalize the atropisomerically enriched quinolines into pharmaceutically privileged scaffolds with minimal observed racemization.

Di-Et alkylor arylphosphonates are treated with OH-containing oligoethers to obtain products which are useful as additives possessing fire resistance in foamed plastics, glass reinforced plastics, and other materials. Di-Et phosphonate and methyl-, allyl-, trichloromethyl-, and phenylphosphonates are used, and the oligoethers are HO[CH2CH2O2CRCO]mOCH2CH2OH, where R = -CH2-CH2-, -CH:CH-, or -o-C6H4-, where m is 1-2. The compounds are heated at 160-80° under N. The quantity of condensate increases after 4-6 hrs. with the acid number increasing and the OH-group content decreasing. Chromatograms, kinetic data, and ir spectra are given for the products and discussed, and a mechanism for the reaction, based on the destruction of the oligoether by alcoholysis, followed by a proton-radical exchange between the oligoether and the Et Cellosolve formed is proposed.

Nandi, Sudipta published the artcileUrea transporter and its specific and nonspecific inhibitors: State of the art and pharmacological perspective, Application of 1-(4-Chlorophenyl)thiourea, the publication is European Journal of Pharmacology (2021), 174508, database is CAplus and MEDLINE.

Hypertension is a major concern for a wide array of patients. The traditional drugs are commonly referred as ′water pills′ and these mols. have been successful in alleviating hypertension. However, this comes at the high expense of precious electrolytes in our body. To dissipate this major adverse effect, the urea transporter inhibitors play especially important roles in maintaining the fluid balance by maintaining the concentration of urea in the inner medullary collecting duct. The purpose of this communication is to provide insights into the structural feature of these target proteins and inhibition of both urea transporter types A (UT-A) and B (UT-B) selectively and non-selectively with a special focus on the UT-A inhibitors as they are the primary target for diuresis. It was observed that a wide class of drugs such as thiourea analogs, 2,7-disubstituted fluorenones can inhibit both the protein non-selectively whereas 8-hydroxyquinoline, aminothiazolone, 1,3,5-triazine, triazolothienopyrimidine, thienoquinoline, arylthiazole, γ-sultambenzosulfonamide and 1,2,4-triazoloquinoxaline classes of compounds inhibit UT-A. The goal of this study is to highlight the important aspects that may be useful to understanding the perspectives of urea transporter inhibitors in rational drug discovery.

Of 11 phosphonic acid esters tested [ROP:O(OR1)R2], the 2 compds, where R = Et, R1 = (CH2)4CCl3, R2 = Me and where R = R1 = Et, R2 = CCl3 had the greatest anticholinesterase activity, inhibiting the enzyme 50% at 8.3 × 10-7 and 7.6 × 10-6 mol/L, resp. The compound where R = R1 = Et, R2 = Me had no anticholinesterase activity and the remaining compounds inhibited the enzyme at concentrations ranging from 5.75 × 10-5 to 6.5 × 10-1 mol/L. The i.p. LD50 values in mice ranged from 720 to 2240 mg/kg, the most active anticholinesterase having the greatest toxicity and the inactive compound having the least. These compounds were less toxic than some presently used in medical practice.

A series of 1-(substituted benzyl)-4-(5-(5-nitroheteroaryl-2-yl)-1,3,4-thiadiazol-2-yl) piperazine derivatives I [X = O, S; R= 3-MeO, 2-O₂N, 2,5-(Cl)₂, 2,4,5-(F)₃, etc.] were synthesized. The synthesized compounds I were evaluated against three metronidazole-resistant isolates of Helicobacter pylori using disk diffusion bioassay test. The results of SAR study indicated that the potency and anti-H. pylori activity profile of synthesized derivatives was mainly attributed to the substituted nitroaryl moiety at the C-5 position of 1,3,4-thiadiazole ring. Compound I [X = O; R = 3-MeO] was found to be the most potent.

A series of novel ‘drug-like’ small mols. based on 1H-benzo[d]imidazole derivatives bearing furan-2-yl, 4-piperidine and 5-aryl/aminoaryl substitutions were designed and synthesized. The key intermediate tert-butyl-4-(5-bromo-2-(furan-2-yl)-1H-benzo[d]imidazol-1-yl)piperidine-1-carboxylate was synthesized via sequential reaction starting from 4-bromo-1-fluoro-2-nitrobenzene. The 5-aryl-substituted mol. library was generated via Suzuki-Miyaura coupling of the key intermediate with various boronic acids while Buchwald coupling with various anilines generated the second mol. library of tert-butyl-4-(2-(furan-2-yl)-5-(arylamino)-1H -benzo[d]imidazol-1-yl)piperidine-1-carboxylates. The structures of all the newly synthesized compounds were confirmed by spectral anal. The optimized procedure gives easy access to two new mol. libraries of 1H-benzo[d]imidazoles with operational simplicity and good yield.
