A safe and scalable continuous flow strategy for Wolff-Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in combination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction conditions (200 degrees C, 50 bar), reactor materials such as stainless steel, glass, or any type of polymer have compatibility problems, rendering this process problematic on a production scale. The use of corrosion-resistant silicon carbide (SiC) as the reactor material opens up the possibility of performing Wolff-Kishner reductions on scale with a considerably improved safety profile. Methanol as the solvent significantly simplifies the workup procedure compared with the generally employed high-boiling solvents such as diethylene glycol. The continuous flow protocol was applied to a number of substrates and provided the desired products in good to high yields with space-time yields of up to 152 g L(-1)h(-1). In addition, a pharmaceutically valuable active pharmaceutical ingredient precursor was synthesized by employing this high-temperature/pressure Wolff-Kishner protocol.

In subsurface bioremediation, electron donor addition promotes microbial Fe(lII)-oxide mineral reduction that could change soil pore structure, release colloids, and alter soil surface properties. These processes in turn may impact bioremediation rates and the ultimate fate of contaminants. Columns packed with water-stable, Fe-oxide-rich soil aggregates were infused with acetate-containing artificial groundwater and operated for 20 d or 60 d inside an anoxic chamber. Soluble Fe(II) and soil colloids were detected in the effluent within one week after initiation of the acetate addition, demonstrating Fe(III)-bioreduction and colloid formation. Diffusible Br-, less diffusible 2,6-difluorobenzoate (DFBA), and non-diffusible silica-shelled silver nanoparticles (SSSNP) were used as tracers in transport experiments before and after the bioreduction. The transport of Br- was not influenced by the bioreduction. DFBA showed earlier breakthrough and less tailing after the bioreduction, suggesting alterations in flow paths and soil surface chemistry during the 20-d bioreduction treatment. Similarly, the bioreduction increased the transport of SSSNP very significantly, with mass recovery increasing from 1.7% to 25.1%. Unexpectedly, the SSSNP was completely retained in the columns when the acetate injection was extended from 20 to 60 d, while the mass recovery of DFBA decreased from 89.1% to 84.1% and Br showed no change. The large change in the transport of SSSNP was attributed to soil aggregate breakdown and colloid release (causing mechanical straining of SSSNP) and the exposure of iron oxide surfaces previously unavailable within aggregate interiors (facilitating attachment of SSSNP). These results suggest a time dependent fashion of microbial effect on the transport of diffusivity-varying tracers. (C) 2018 Elsevier Ltd. All rights reserved.

Cinnamic acid and its derivatives are known for anti-tubercular activity. The present study reports the synthesis of cinnamic acid derivatives via bioisosteric replacement of terminal carboxylic acid with oxadiazole. A series of cinnamic acid derivatives (styryl oxadiazoles) were designed and synthesized in good yields by reaction of substituted cinnamic acids (2, 15a-15s) with amidoximes. The synthesized styryl oxadiazoles were evaluated in vitro for anti-tubercular activity against Mycobacterium tuberculosis (Mtb) H37Ra strain. The structure-activity relationship (SAR) study has identified several compounds with mixed anti-tubercular profiles. The compound 32 displayed potent anti-tubercular activity (IC50= 0.045 mu g/mL). Molecular docking studies on mycobacterial enoyl-ACP reductase enzyme corroborated well with the experimental findings providing a platform for structure based hit-to-lead development.

A series of quinoline-chalcone (E)-1-[3 or 4-(7-chloroquinolin-4-ylamino) phenyl]-3-(phenyl substituted) prop-2-ene-1-one (4, 5), and quinoline-pyrazoline hybrids 7-Chloro-N-[3 or 4-(4,5-dihydro-5-(phenyl-substituted)-1H-pyrazol-3-yl] phenyl) quinoline-4-amine (6, 7) were synthesized with the aim of achieving an antimalarial and anticancer dual action. Most of the compounds showed significant inhibition (%>80) of beta-hematin formation. The existing structures were tested in vivo as potential antimalarials in mice infected with P. berghei ANKA, chloroquine susceptible strain. Some of the compounds exhibited antimalarial activity comparable to that of chloroquine. Moreover, the compounds induce cell death on two human cancer cell lines (Jurkat E6.1 and HL60) without affecting the primary culture of human lymphocytes. Flow cytometry analysis confirmed the increase in apoptotic cell death after 24 h. Based on the structural analysis, these quinoline hybrids represent new compounds potentially useful for malaria end leukemia treatments.

An efficient, cost-effective, transition-metal-free, oxidative C-H cross-dehydrogenative coupling via a C-H bond functionalization protocol for the regioselective direct C-3 acylation/benzoylation of substituted 2H-Indazoles 1a-m with substituted aldehydes 2a-q/benzyl alcohols 5a-e/styrenes 6a-e is reported. The operationally simple protocol proceeds in the presence of tert-butyl peroxybenzoate (TBPB) as an oxidant in chlorobenzene (PhCl) as a solvent at 110 degrees C for 24 h under an inert atmosphere, which furnished a diverse variety of substituted 3-(acyl/benzoyl)-2H-indazoles 3a-q/4a-l in up to 87% yields. The reaction involves a free-radical mechanism and proceeds via the addition of an in situ generated acyl radical (from aldehydes/benzyl alcohols/styrenes) on 2H-indazoles. The functional group tolerance, broad substrate scope, control/competitive experiments and gram-scale synthesis and its application to the synthesis of anti-inflammatory agent 11 and novel indazole-fused diazepine 13 further signify the versatile nature of the developed methodology.

Herein, we report an unprecedented, fast, highly efficient, transition-metal-free, modified Favorskii reaction-type direct alkynylation and (E)-alkenylation protocol towards the synthesis of alpha,beta-unsaturated ketones and propargyl alcohols that proceeds using the combination of Cs2CO3 and Et3N as weak bases in up to 99% yields. In this reaction, aromatic aldehydes afforded alpha,beta-unsaturated ketones and aliphatic aldehydes furnished propargyl alcohols, respectively. A proposed mechanistic pathway illustrates the involvement of weak base-assisted propargylation of carbonyl compounds followed by allenol-enone tautomerism to furnish (E)-alkenylated product.

A novel, quick, environmentally safe, and one-pot synthesis of a series of N,N-bis(cyanoacetyl)hydrazine derivatives, bis-imino-2H-chromenes and bis-2-oxo-2H-chromene derivatives have been designed. Some selected newly synthesized compounds were investigated in vitro for their antibacterial activity. Compound 5j is the most toxic compound against Staphylococcus aureus with activity index 171%, followed by compound 15b with activity index 136% compared to standard drug ampicillin. Moreover, compound 15a is the most toxic compound against Escherichia coli with activity index 111% compared to standard drug gentamicin. Minimum inhibitory concentration (MIC) was carried out for compounds with high antibacterial activity. Compound 5j has good MIC (7.8 mu g/ml) against Staphylococcus aureus while 15a has good MIC (31.25 mu g/ml) against Streptococcus mutans which is better than MIC of the standard drug ampicillin (MIC = 62.5 mu g/ml). Compounds 5j, 5k, 15a, 15b and 15e which have good MIC values were introduced to enzyme assay against DNA gyrase and topoisomerase IV. The results showed that compound 15a can strongly inhibit DNA gyrase and topoisomerase IV (IC50 = 27.30 and 25.52 mu M respectively), compared to methotrexate as the standard drug (IC50 = 29.01 and 23.55 mu M respectively). Structure-activity relationships were also discussed based on the biological and docking simulation results.
