A simple and efficient method has been developed for the synthesis of 3-hydroxy-2-oxoindole derivatives through a direct vinylogous aldol reaction of allylic esters with isatins, catalyzed by 1,5,7-triazabicyclodec-5-ene. This method affords a variety of 3-hydroxy-2-oxoindole derivatives in moderate to excellent yields with high regioselectivities. An asymmetric version of this reaction catalyzed by Corey’s chiral guanidine proceeded with moderate enantioselectivity. The protocol can also be used to synthesize isatin spiro ethers.

1,2,4-Triazole is a very important scaffold in medicinal chemistry due to the wide spectrum of biological activities and mainly antifungal activity of 1,2,4-triazole derivatives. The main mechanism of antifungal action of the latter is inhibition of 14-alpha-demethylase enzyme (CYP51). The current study presents synthesis and evaluation of eight triazole derivatives for their antimicrobial activity. Docking studies to elucidate the mechanism of action were also performed. The designed compounds were synthesized using classical methods of organic synthesis. The in vivo evaluation of antimicrobial activity was performed by microdilution method. All tested compounds showed good antibacterial activity with MIC and MBC values ranging from 0.0002 to 0.0069 mM. Compound 2 h appeared to be the most active among all tested with MIC at 0.0002-0.0033 mM and MBC at 0.0004-0.0033 mM followed by compounds 2f and 2g. The most sensitive bacterium appeared to be Xanthomonas campestris while Erwinia amylovora was the most resistant. The evaluation of antifungal activity revealed that all compounds showed good antifungal activity with MIC values ranging from 0.02 mM to 0.52 mM and MFC from 0.03 mM to 0.52 mM better than reference drugs ketoconazole (MIC and MFC values at 0.28-1.88 mM and 0.38 mM to 2.82 mM respectively) and bifonazole (MIC and MFC values at 0.32-0.64 mM and 0.64-0.81 mM). The best antifungal activity is displayed by compound 2 h with MIC at 0.02-0.04 mM and MFC at 0.03-0.06 mM while compound 2a showed the lowest activity. The results showed that these compounds could be lead compounds in search for new potent antimicrobial agents. Docking studies confirmed experimental results.

The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

We have synthesized and characterized two small libraries of 2-OMe or 2-NO2-benzene analogues 2a-i and 3a-i containing a wide variety of leaving groups. Irradiation of these compounds at 350 nm generated benzyl radicals that were spontaneously oxidized to benzyl cations directly producing DNA interstrand cross-links (ICLs). Compounds with a 2-methoxy substituent showed a faster cross-linking reaction rate and higher ICL efficiency than the corresponding 2-nitro analogues. Apart from the aromatic substituent, the benzylic leaving groups greatly affected DNA cross-linking efficiency. Higher ICL yields were observed for compounds with OCH3 (3b), OCH2Ph (3d), or Ph3P+ (3i) as leaving groups than those containing OAc (3a), NMe2 (3e), morpholine (3f), OCH2CH=CH2 (3c), SPh (3g), or SePh (3h). The heat stability study of the isolated ICL products indicated that dGs were the preferred alkylation sites in DNA for the benzyl cations produced from 2a-i, 3c, and 3e-i while 3a (L = OAc), 3b (L = OMe), and 3d (L = OCH2Ph) showed a similar photoreactivity toward dGs and dAs. Although the photogenerated benzyl cations alkylated dG, dC, and dA, ICL assay with variation of DNA sequences showed that the ICL reaction occurred with opposing dG/dC but not with staggered dA/dA.

A practical phosphorylation for generating organophosphates and phosphoramidates via electrochemical dehydrogenative cross-coupling of P(O)H compounds with arenols and anilines is disclosed. This method involves using inorganic iodide salts as both redox catalysts and electrolytes in an undivided cell without the addition of oxidants or bases. A preliminary mechanistic study suggests that radicals are not involved in this process. This method is green and eco-friendly and has good functional group tolerance, high yields and broad substrate scope, with the potential for practical synthesis.

1,2,3-Triazole contained conjugated porous polymers (CPPs) have recently emerged as a new class of efficient photocatalysts. To gain more insight into the excellent photocatalytic activity of this kind of CPPs, herein, we report the design and preparation of a series of 1,2,3-triazole-based CPPs via oxidative coupling polymerization to study their photocatalytic performance. These CPPs have donor-acceptor properties and 1,2,3-triazole serves as an electron acceptor. The resulting CPPs with thiophene, carbazole and diphenylamine as electron donor units, respectively, have distinct porosities and optoelectronic properties, and showed effective photocatalytic performance towards oxidative hydroxylation of arylboric acids and alkylation of vinylarenes with diethyl bromomalonate or bromoacetonitrile. The thiophene contained CPP was a more efficient photocatalyst for the catalytic reactions, which can be attributed to its smaller optical band gap and greater charge separation effi-ciency. Furthermore, PTPT has shown reliable recyclability with no significant loss in its catalytic activity.

In the enantioselecitve hydrogenation of (E)-2-methyl-2-butenoic acid (1) over a cinchonidine-modified Pd/C catalyst, the addition of hydrogen preferentially proceeds from the Re-Si enantioface of the C=C double bond of 1 to yield (S)-2-methylbutanoic acid ((S)-3). Double bond migration of 1 takes place under the reaction conditions and is followed by immediate hydrogenation to yield 3 in a poor enantiomeric purity. Deuterium labeling experiments at 0.1 MPa and 1.9 MPa of D-2 verified the previous assumption of competitive double bond migration. The combination of isotopic labeling experiments and chiral analysis revealed that the double bond migration of 1 proceeds with the same enantiofacial differentiation as the hydrogenation of 1. Thus, interaction of 1 with cinchonidine adsorbed on the Pd surface may control the configuration of the double bond migration and the hydrogenation.

A modest, competent and green synthetic procedure for novel coumarinyl-1,3,4-oxadiazolyl-2mercaptobenzoxazoles 8i-t has been reported. Analysis of the docked (PDB ID: 5IKR; A-Chain) poses of the compounds illustrated that they adopt identical conformations to the extremely selective COX-2 inhibitor. The biological outcomes as well as computational study suggested that the compounds originated to have elevated resemblance towards COX-2 enzyme than COX-1. The compounds 8i, 8l, 8q, 8r, 8s and 8t emerged as most potent and selective COX-2 inhibitors in contrast with Mefenamic acid. The selectivity index of 8l, 8n and 8r was respectively found to be 33.95, 20.25 and 24.98 which manifested their high selectivity against COX-2. Interestingly, the compounds which were active as COX-2 inhibitors were also active as antioxidant agents.

A series of amides based on (2S)-cyanopyrrolidine and alpha, beta-unsaturated aryl- and hetarylcarboxylic acids have been synthesized. The dependence of the hypoglycemic activity of compounds on the structure of the aromatic fragment has been studied in the oral glucose tolerance test in mice. Amides based on (E)-3-phenylprop-2-enoic and (E)-3-(4-methoxyphenyl)prop-2-enoic acids and (2S)-cyanopyrrolidine have been shown to significantly reduce blood glucose levels in mice. The observed hypoglycemic effect at a dose of 10 mg/kg is comparable to the effect of hypoglycemic drug vildagliptin.

A series of highly CO2-soluble open-chain crown ether bridged diphosphates were designed and prepared as chelating ligands which were used to extract lanthanide ions from cellulose paper into supercritical CO2 (ScCO2). These ligands were designed by introducing different ester side chains and joining the two phosphorus groups with different length of ethylene oxide group which could provide enhanced solubility and complexation ability. The solubility data of these synthesized diphosophates in ScCO2 were measured at 313.15 K and 10.65 MPa-13.69 MPa. Lanthanides metal ions including La3+, Ce3+, Pr3+, Nd3+, Sm3+, Gd3+, Er3+, and Yb3+ were successfully removed from the solid matrix by supercritical fluid extractions using these chelating ligands at 313.15 K and 20 MPa. The extraction efficiency of metal ion was affected by chelating ligands’ side chain, which increased from 68% to 94% mainly driven by the increased solubility capability.
