The widespread presence of secondary amines in agrochemicals, pharmaceuticals, natural products, and small-molecule biological probes has inspired efforts to streamline the synthesis of molecules with this functional group. Herein, we report an operationally simple, mild protocol for the synthesis of secondary amines by three-component alkylation reactions of imines (generated in situ by condensation of benzaldehydes and anilines) with unactivated alkyl iodides catalyzed by inexpensive and readily available Mn-2(CO)(10). This protocol, which is compatible with a wide array of sensitive functional groups and does not require a large excess of the alkylating reagent, is a versatile, flexible tool for the synthesis of secondary amines.

In this report, tetrabutylammonium tribromide (TBATB) was introduced as an efficient visible light active catalyst to carry out the aerobic oxidation of toluene, its derivatives, and some of methyl arenes to benzaldehydes, benzoic acids and ketones in good to high yields. All the oxidation reactions were performed under mild conditions using oxygen as a green oxidant, a catalytic amount of TBATB under blue (460 nm), royal blue (430 nm), and violet LED (400 nm) irradiation. It was found that the reactions selectivity was significantly affected by changing the solvent (from CH3CN to EtOAc) and LED wavelength (from blue to violet). In the following, our mechanistic studies revealed that the visible light oxidation of toluenes and methyl arenes over TBATB could be following a benzyl peroxy radical intermediate.

Cellulose catalyzed oxidative hydroxylation of aryl and hetero-arylboronic acids to the corresponding phenols under metal and base free strategy has been demonstrated. The sustainable ipso-hydroxylation takes place using hydrogen peroxide as an oxidant in water under mild condition in shorter period of time. Interestingly, easy recovery and reusability of heterogeneous catalyst without significant loss in catalytic yield makes the protocol environmentally benign. (C) 2019 Elsevier Ltd.

A novel photoactive porous material of GR/FeMIL-101 based on FeMIL-101 metal organic frameworks (MOFs) was successfully synthesized via a simple hydrothermal method. The structural and photoelectric properties of the GR/FeMIL-101 was analyzed by XRD, SEM, TEM, TGA, XPS, UV-vis DRS, FT-IR, PL and EIS methods. The photocatalytic performance for the selective oxidation of benzyl alcohol with GR/FeMIL-101 as catalysts was evaluated under visible light irradiation. The results showed that the GR/FeMIL-101 nanohybrid had better photocatalytic performance than both of FeMIL-101 and the pristine MIL-101. It was further found that the incorporation of Fe and MIL-101 caused valence fluctuations of Fe3+/Fe2+ which improved the absorption of visible-light and increased the separation efficiency of photogenerated charges. In addition, the combination of FeMIL-101 and GR could further promote the transfer rate of the photoelectrons. The mechanism of the reaction revealed that center dot O-2(-) was the dominating active specie in this reaction through active species trapping experiments. [GRAPHICS] .

Copper porphyrin-catalyzed construction of ether bond by cross-dehydrogenative coupling of sp [3] C-H bond with phenols bearing electron-withdrawing groups (EWG) was described for the first time. A broad range of substrates afforded different acetals in moderate to excellent yields with good functional group tolerance. The developed method is not only suitable for phenol substrates with ortho-directing groups, but also suitable for those phenol without ortho-directing groups. Significantly, a high turnover number (TON) up to 7300 was achieved in gram-level test. (C) 2020 Elsevier Ltd. All rights reserved.

In the presence of [p-cymene)RuCl2](2), (E)-configured alkenyl bromides couple with aromatic carboxylates to form orthovinylbenzoic acids. This C-H vinylation proceeds in high yields without any activating phosphine ligands and has an excellent functional group tolerance. Starting from commonly available (E/Z)-mixtures of alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.

Background Baloxavir marboxil (baloxavir) is a new anti-influenza virus agent that is comparable to oseltamivir phosphate (oseltamivir). Since the efficacy of baloxavir in preventing household transmission of influenza is not well established, we compared the secondary household influenza virus transmission rates between patients on baloxavir vs oseltamivir. Methods Between October 2018 and March 2019, we enrolled index patients (diagnosed with influenza and treated with baloxavir or oseltamivir) and household members. The secondary attack rate of household members was compared between index patients treated with baloxavir vs oseltamivir. Risk factors of household transmission were determined using multivariate logistic analyses. Results In total, 169 index patients with influenza type A were enrolled. The median age was 27.0 (interquartile range; 11-57) years. The number of index patients treated with baloxavir and oseltamivir was 49 and 120, respectively. The secondary attack rate was 9.0% (95% confidence interval [CI]: 4.6-15.6) in the baloxavir group and 13.5% (95% CI: 9.8-17.9) in the oseltamivir group. In the multivariate analysis, independent risk factors were 0-6 years of age (odds ratio [OR] 2.78, 95% CI: 1.33-5.82,p < 0.01) and not being on baloxavir treatment. (OR: 0.63, 95% CI: 0.30-1.32,p = 0.22). Conclusion The household secondary attack rate of influenza was comparable in patients treated with baloxavir vs oseltamivir. Therefore, baloxavir can be used as an alternative therapy to oseltamivir in reducing household transmission of influenza. Recommanded Product: 98-17-9.

Recently, inhibition of carbonic anhydrase (hCA) and acetylcholinesterase (AChE) have appeared as a promising approach for pharmacological intervention in a variety of disorders such as glaucoma, epilepsy, obesity, cancer, and Alzheimer’s disease. Keeping this in mind, N, N’-bis[(1-aryl-3-heteroaryl) propylidene] hydrazine dihydrochlorides, N1-N11, P1, P4-P8, and R1-R6, were synthesized to investigate their inhibitory activity against hCA I, hCA II, and AChE enzymes. All compounds in N, P, and R-series inhibited hCAs (I and II) and AChE more efficiently than the reference compounds acetazolamide (AZA), and tacrine. According to the activity results, the most effective inhibitory compounds were in R-series with the K-i values of 203 +/- 55-473 +/- 67 nM and 200 +/- 34-419 +/- 94 nM on hCA I, and hCA II, respectively. N, N’-Bis[1-(4-fluorophenyl)-3-(morpholine-4-yl) propylidene] hydrazine dihydrochlorides, N8, in N-series, N, N’-Bis[1-(4-hydroxyphenyl)-3-(piperidine-1-yl) pro-pylidene] hydrazine dihydrochlorides, P4, in P-series, and N, N’-bis[1-(4-chlorophenyl)-3-(pyrrolidine-1-yl) pro-pylidene] hydrazine dihydrochlorides, R5, in R-series were the most powerful compounds against hCA I with the K-i values of 438 +/- 65 nM, 344 +/- 64 nM, and 203 +/- 55 nM, respectively. Similarly, N8, P4, and R5 efficiently inhibited hCA II isoenzyme with the K-i values of 405 +/- 60 nM, 327 +/- 80 nM, and 200 +/- 34 nM, respectively. On the other hand, P-series compounds had notable inhibitory effect against AChE than the reference compound tacrine and the K-i values were between 66 +/- 20 nM and 128 +/- 36 nM. N, N’-Bis[1-(4-fluorophenyl)-3-(piperidine-1-yl) propylidene] hydrazine dihydrochlorides, P7, was the most potent compound on AChE with the K-i value of 66 +/- 20 nM. The other most promising compounds, N, N’-bis[1-(4-hydroxyphenyl)-3-(morpholine-4-yl) propylidene] hydrazine dihydrochlorides, N4 in N-series and N, N’-bis[1-(4-hydroxyphenyl)-3-(pyrrolidine-1-yl) propylidene] hydrazine dihydrochlorides, R4 in R-series were againts AChE with the K-i values of 119 +/- 20 nM, 88 +/- 14 nM, respectively.

Histone lysine-specific demethylase 1 (LSD1) was the first discovered histone demethylase. Inactivating LSD1 or downregulating its expression inhibits cancer-cell development, and thus, it is an attractive molecular target for the development of novel cancer therapeutics. In this study, we worked on the structural optimization of natural products and identified 30 novel LSD1 inhibitors. Utilizing a structure-based drug design strategy, we designed and synthesized a series of curcumin analogues that were shown to be potent LSD1 inhibitors in the enzyme assay. Compound WB07 displayed the most potent LSD1 inhibitory activity, with an IC50 value of 0.8 mu M. Moreover, WA20 showed an anticlonogenic effect on A549 cells with an IC50 value of 4.4 mu M. Molecular docking simulations were also carried out, and the results indicated that the inhibitors bound to the protein active site located around the key residues of Asp555 and Asp556. These findings suggested that compounds WA20 and WB07 are the first curcumin analogue-based LSD1 inhibitors with remarkable A549 suppressive activity, providing a novel scaffold for the development of LSD1 inhibitors.
