Dialkylation of Indoles with Trichloroacetimidates to Access 3,3-Disubstituted Indolenines

2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural products and medicinally relevant small molecule structures. This method provides an alternative to the use of transition metal catalysis. The indolenines are readily transformed into spiroindoline systems which are privileged scaffolds in medicinal chemistry.

Newly isolated Bacillus sp. PS-6 assisted phytoremediation of heavy metals using Phragmites communis: Potential application in wastewater treatment

This work aimed to study Bacillus sp. PS-6 assisted phytoremediation of metals from pulp and paper industry wastewater as a novel green technique for the removal of metals of wastewater. Results revealed that heavy metal (mg L-1) contents in wastewater were reduced after in-situ phytoremediation for Fe, Cu, Zn, Cd, Mn, Ni, Pb, and As. Phragmites communis showed higher potential for the enrichment of Fe, Cu, Zn, Cd, Mn, Ni, Pb, and As in its rhizomes, roots, and shoots compared to leaves. The strain produced indole acetic acid, siderophores, and hydrolytic and ligninolytic enzymes, and resulted in nutrients solubilization. Results offer potential basis for the removal of metals from pulp and paper industry wastewater at large scale and prevention of pollution.

Copper-Catalyzed Sequential C(sp(2))/C(sp(3))-H Amination of 2-Vinylanilines with N-Fluorobenzenesulfonimide

An oxidative C-H diamination of 2-vinylanilines with N-fluorobenzenesulfonimide (NFSI) was developed for the efficient synthesis of indole frameworks. The reaction proceeded via sequential intra-/intermolecular diamination of C(sp(2))-H and C(sp(3))-H bond, incorporating one nitrogen from the substrate and the other nitrogen from the NFSI.

SYNTHESIS OF DIBENZO[cd, g]INDOLE

In this paper, a synthesis method is proposed and discussed for a compound not previously described – dibenzo [cd, g] indole. For the successful synthesis of the target compound we used the classical method based on well-known procedure of indoles obtaining according to Fisher method with some changes. Commercially available derivatives of anthracene were used as the starting compound since they already contain a ready-made system of three condensed aromatic rings and they reaction activity is rather high. The corresponding diazonium salt was obtained from 9-amino anthracene by reaction with ethyl nitrite. Attempts to obtain the diazonium salt by reaction the amine with inorganic nitrites in an acidic aqueous medium did not lead to a product with an acceptable yield. 9-Antryl hydrazine was prepared by reducing the diazonium salt under mild conditions. Reduction was carried out using sulfur dioxide in aqueous sodium hydrosulfite. Formaldehyde of 9-anthrylhydrazone was obtained from anthrylhydrazine after condensation with paraformaldehyde. The target product was obtained by intramolecular cyclization of hydrazone under the action of BF3 * Et2O under the condition of high dilution and low temperature. The physicochemical characteristics of all the obtained compounds are determined. Melting point was determined on a Stuart SMP-30 instrument. IR spectra were recorded on a Nicolet 380 FT-IR spectrometer in tablets with potassium bromide. NMR spectra were recorded on a Bruker DRX-400 spectrometer (400 MHz), Me4Si was used as a H-1 standard, in CDCl3 as a solvent. Elemental analysis was performed on a EuroEA 3000 analyzer. Based on the data from the above analysis methods, it was concluded that the proposed structures correspond to the real ones. In addition, we can conclude that synthesized products are individual substances.

Synthesis of C2-tetrasubstituted indolin-3-ones via Cu-catalyzed oxidative dimerization of 2-aryl indoles and cross-addition with indoles

An efficient protocol for the synthesis of 2,2-disubstituted indolin-3-ones under mild conditions has been developed. This reaction involves the copper-catalyzed in situ oxidative de-aromatization of 2-arylindoles to indol-3-one, followed by self-dimerization as well as cross-addition with indoles under mild conditions.

Determination of indoles in plasma of polycystic ovarian syndrome patients by high performance liquid chromatography-fluorescence detection

A new method was established for the determination of indoles (indole (IND), 3methylindole (3 -MI), indolyl-3-acetic acid (IAA) and indolyl-3-propionic acid (IPA)) in plasma by high performance liquid chromatography-fluorescence detection (HPLC-FLD). The analytes were separated simultaneously on a Shim -pack VP-ODS column (150 mmx4. 6 mm, 4. 6 tim) using 15 mmol/L sodium dihydrogen phosphate solution and methanol (48 :52, v/v) as the mobile phases. The column temperature was 30 C, and the flow rate was 0. 8 mL/min. The calibration curves of IND, 3 -MI, IPA and IAA showed good linear relationships. The intra-day and inter-day relative standard deviations (RSDs) for the analytes were both less than 6. 31%. The average recoveries of the analytes in plasma were 97. 5% 107. 0%. The method was successfully applied to the analysis of indoles in the plasma of healthy women of reproductive age (n = 25) as controls and patients with polycystic ovarian syndrome (n = 61). The results showed that the concentrations of indoles in the plasma were significantly different between the two groups, and IND was found to be a risk factor and a potential diagnostic biomarker for polycystic ovarian syndrome (PCOS). The method is simple, sensitive and suitable for use in clinical testing and laboratory research.

Azospirillum brasilense reduces oxidative stress in the green microalgae Chlorella sorokiniana under different stressors

In this study, we investigated oxidative stress in the green microalgae, Chlorella sorokiniana, in co-culture with the plant growth promoting bacteria (PGPB), Azospirillum brasilense. This relationship was studied in the absence of an exogenous stressor, under copper stress, and under nitrogen limitation stress. We confirmed that copper and nitrogen limitation induced algal oxidative stress and reductions in chlorophyll content. In all cases, the presence of A. brasilense lowered the accumulation of intracellular reactive oxygen species (ROS) while promoting chlorophyll content. This effect was driven, in part, by A. brasilense’s secretion of the auxin hormone, indole-3-acetic acid, which is known to mitigate stress in higher plants. The findings of the present study show that stress mitigation by A. brasilense resulted in suppressed starch accumulation under nitrogen limitation stress and neutral lipid accumulation under copper stress. In fact, A. brasilense could almost completely mitigate oxidative stress in C. sorokiniana resulting from nitrogen limitation, with ROS accumulation rates comparable to the axenic control cultures. The biotechnological implication of these findings is that co-culture strategies with A. brasilense (and similar PGPB) are most effective for high growth applications. A second growth stage may be needed to induce accumulation of desired products.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 120-14-9. Computed Properties of C9H10O3.
