Synthesis of Indoles by Palladium-Catalyzed Reductive Cyclization of beta-Nitrostyrenes with Carbon Monoxide as the Reductant

An efficient catalytic cyclization of beta-nitrostyrenes to indoles was developed. The reaction was applied to the synthesis of 3-arylindoles and 2-alkylindoles. Given that in the latter case the starting beta-nitrostyrenes can be easily obtained by a Henry reaction, the present method allows indoles to be obtained in a two-step sequence starting from cheap reactants.

Newly synthesized indolium-based ionic liquids as unprecedented inhibitors for the corrosion of mild steel in acid medium

New indolium-based ionic liquids (IBILs) of chemical formula 5-methoxy-1,2,3,3-tetramethyl-3H-indolium iodide (IBIL-I), 1-(2-carboxyethyl)-2,3,3-trimethyl-3H-indolium iodide (IBIL-II), 2,3,3-trimethyl-1-(pyren-2-ylmthyl)-3H-indolium iodide (IBIL-III), 1-(3-ethoxy-3-oxopropyl)-2,3,3-trimethyl-3H-indolium bromide (IBIL-IV) and 1-(2-ethoxy-2-oxoethyl)-2,3,3-trimethyl-3H-indolium bromide (IBIL-V) have been synthesized and characterized. The adsorption and corrosion inhibition effect of those IBILs have been studied using polarization measurements and cyclic voltammetry. It has been found that the inhibitive effect of the corrosion of mild steel in 0.5 M H2SO4 is inherently dependent on the structure of the studied IBILs; IBILs with bromide as an anionic head are more efficient than those with iodide. Thermodynamic calculations indicated that the adsorption on steel surface accords with Langmuir adsorption isotherm. Electrochemical measurements showed that the IBIL-IV, with the highest inhibition efficiency, acted mainly as a mixed type inhibitor, albeit the inhibition of the anodic branch is larger than the cathodic one. Cyclic voltammetric measurements at polycrystalline gold electrode gave an insight into the mechanism of corrosion inhibition by the studied ionic liquids.

Interaction of plant growth promoting bacteria with tomato under abiotic stress: A review

Tomato is one of the most demanding/utilizable vegetable crops worldwide after potato. It is extensively cultivated throughout the tropics and sub-tropics around the world. However, certain climate change consequences like salinity, drought, and environmental pollutants particularly heavy metals etc., lead to low soil productivity. In fact, problem of salinity, drought and soil contamination are increasing rapidly throughout the globe and severely affecting more than 10% of arable land resulting into reduction of more than 50% average yields of major crops including tomato. Therefore, sustainable agriculture is in great demand under current alarming condition of food security. Plant growth promoting bacteria (PGPB) has been evident as a co-evolution between plants and microbes showing antagonistic and synergistic interactions. Therefore, utilization of PGPB to tackle the problem of salinity, drought and heavy metal contamination is one of the novel biological approaches for sustainable agriculture practices. Under stress conditions, plant hormone like ethylene is known to endogenously regulate the homeostasis of plants leading to significant reduction in root and shoot growth. Few PGPB like Pseudomonas sp. and Bacillus sp. have developed tolerance mechanism against varieties of heavy metals through mobilization, surface complexation, biosorption, precipitation, intracellular compartmentalization or immobilization processes. Looking into the multiple applications of PGPB in sustainable agriculture, scientists and policy makers are currently emphasizing over selection of suitable microbial communities through interdisciplinary research disciplines including agriculture, biotechnology, chemical engineering, environmental science and nanotechnology to bring together different ecological and functional biological approaches to provide new formulations and opportunities with immense potential. The present review entails the overview of current trends in PGPB mediated abiotic stress amelioration in order to encounter the negative impacts of changing climatic conditions for sustainable enhancement in tomato productivity.

Copper-catalyzed N-arylation of azoles and diazoles using highly functionalized trivalent organobismuth reagents

The N-arylation of indoles, indazoles, pyrroles, and pyrazoles using highly functionalized trivalent arylbismuth reagents is reported. The reaction is promoted by a substoichiometric amount of copper acetate, and it tolerates a wide diversity of functional groups on the azole and the organobismuth reagent. The method is also applied to the N-arylation of tryptophan derivatives. This journal is the Partner Organisations 2014.

(1-Nosyl-5-nitroindol-3-yl)methyl ester: A novel protective group for carboxylic acids

(Chemical Equation Presented) The usefulness of (1-nosyl-5-nitroindol-3-yl) methyl esters as a novel protective group for carboxylic acid is fully demonstrated. The novel protective group is stable under a broad range of conditions and can easily be deprotected under the mild conditions used for removal of the nosyl (Ns) group. It is orthogonal to the existing protective groups for carboxylic acids such as t-butyl and allyl esters.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 6625-96-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6625-96-3, in my other articles.

A simple and facile synthesis of novel 1,2,3-triazole substituted pyrimidine derivatives

A series of novel indole and pyrimidine scaffolds bearing 1,2,3-triazoles have been designed and synthesized using click chemistry reaction conditions. Target compounds 9a-j were synthesized in the multi-step process. In the first step 5-substituted-1-methyl-1H-indole-3-carbaldehyde 2a-b reacted with ethyl cyanoacetate 3 and guanidine hydrochloride 4 in presence of L-Proline in ethanol undergoes cyclisation to form 5a-b. Further, 5a-b condensed with various benzaldehydes to form Schiff’s base 6a-f, which further proporgylated with propargyl bromide to form 7a-f. Finally, 7a-f was subjected to click-chemistry with various azides in the presence of CuSO4.5H2O + sodium ascorbate mixture in Dimethylformamide at room temperature to obtain 2 + 3 cycloaddition products 9a-j in high yield. All these synthetic methods are mostly green and inexpensive with excellent yields.

A magnetic metal-organic framework as a highly active heterogeneous catalyst for one-pot synthesis of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives

A novel magnetic metal-organic framework, NiFe2O4@MOF-5, has been prepared and characterized using spectroscopic, microscopic, and magnetic techniques (FT-IR, XRD, TEM, SEM, EDX, and VSM). This magnetically separable catalyst exhibited high catalytic activity for the synthesis of a variety of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives via a one-pot, three-component reaction of aldehyde, indole, and kojic acid under solvent-free conditions. The catalyst can be easily magnetically separated and exhibits significant recyclability, with no significant loss of activity after six consecutive runs.

One-pot tandem synthesis of 2,3-unsubstituted indoles, an improved Leimgruber-Batchoindole synthesis

A concise, fast and efficient one-pot methodology has been developed for preparing 2,3-unsubstituted indoles from 2-nitrotoluenes and dimethylformamide dimethyl acetal. Compared with the classical Leimgruber-Batcho reaction, such a one-pot process simplified the operation procedures, generated less by-products and chemical residues, and resulted in higher overall yields in a shorter reaction time.
