3-Alkylated indoles by reduction of sulfonyl indoles under flow chemical conditions

Reduction of 3-(1-arylsulfonylalkyl) indoles (sulfonyl indoles) using polymer-supported sodium borohydride under flow chemical conditions allows an efficient synthesis of 3-alkylindoles with a notable waste minimization and reduced solvent consumption. The flow conditions can be also applied to the synthesis of sulfonyl indoles which can be obtained by a three-component coupling of indoles with aldehydes and p-toluenesulfinic acid. Using the two-step flow chemical approach, 3-alkylindoles can be directly obtained from their remote indole and aldehyde precursors. [GRAPHICS] .

Synthesis of Some Novel Fused Pyrimido[4 ”,5 ”:5 ‘,6 ‘]- [1,2,4]triazino[3 ‘,4 ‘:3,4] [1,2,4]triazino[5,6-b]indoles with Expected Anticancer Activity

Our current goal is the synthesis of polyheterocyclic compounds starting from 3-amino[1,2,4]triazino[5,6-b]indole 1 and studying their anticancer activity to determine whether increasing of the size of the molecules increases the anticancer activity or not. 1-Amino[1,2,4]triazino[3′,4′:3,4][1,2,4]triazino[5,6-b]indole-2-carbonitrile (4) was prepared by the diazotization of 3-amino[1,2,4]triazino[5,6-b]indole 1 followed by coupling with malononitrile in basic medium then cyclization under reflux to get 4. Also, new fused pyrimido[4 ”,5 ”:5′,6′-b][1,2,4]triazino-[3′,4′:3,4][1,2,4]triazino[5,6-b]indole derivative 6 was prepared and used to obtain polycyclic heterocyclic systems. Confirmation of the synthesized compounds’ structures was carried out using elemental analyses and spectral data (IR, H-1-NMR and C-13-NMR and mass spectra). The anticancer activity of some of the synthesized compounds was tested against HepG2, HCT-116 and MCF-7 cell lines. The anticancer screening results showed that some derivatives display good activity which was more potent than that of the reference drug used. Molecular docking was used to predict the binding between some of the synthesized compounds and the prostate cancer 2q7k hormone and breast cancer 3hb5 receptors.

A prospectus of plant growth promoting endophytic bacterium from orchid (Vanda cristata)

Background A plant growth-promoting endophytic bacterium PVL1 isolated from the leaf of Vanda cristata has the ability to colonize with roots of plants and protect the plant. PVL1 was isolated using laboratory synthetic media. 16S rRNA gene sequencing method has been employed for identification before and after root colonization ability. Results Original isolated and remunerated strain from colonized roots were identified as Bacillus spp. as per EzBiocloud database. The presence of bacteria in the root section of the plantlet was confirmed through Epifluorescence microscopy of colonized roots. The in-vitro plantlet colonized by PVL1 as well as DLMB attained higher growth than the control. PVL1 capable of producing plant beneficial phytohormone under in vitro cultivation. HPLC and GC-MS analysis suggest that colonized plants contain Indole Acetic Acid (IAA). The methanol extract of Bacillus spp., contains 0.015 mu g in 1 mu l concentration of IAA. PVL1 has the ability to produce antimicrobial compounds such as ethyl iso-allocholate, which exhibits immune restoring property. One-way ANOVA shows that results were statistically significant at P <= 0.05 level. Conclusions Hence, it has been concluded that Bacillus spp. PVL1 can promote plant growth through secretion of IAA during root colonization and ethyl iso-allocholate to protect plants from foreign infections. Thus, this study supports to support Koch's postulates of bacteria establishment. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Synthesis of pyrroloindolines through formal [3+2]-cycloaddition of indoles with chiral N-2-acetamidoacrylyl oxazolidinones

Chiral N-2-acetamidoacrylyl oxazolidinones were produced and reacted with indoles under Lewis acid conditions to generate hexahydropyrrolo[2,3-b]indole products in a formal [3 + 2] cycloaddition process. Optimal conditions included the use of tin(IV) chloride in methylene chloride at 0 degrees C. Pyrroloindoline products were obtained from various indoles with shorter reaction times (12 hr) up to 91% yield with high, >20:1 exo selectivity. A mechanism involving reversible conjugate addition followed by an enamine lone-pair-iminium capture, tautomerization, and tin-enolate protonation accounts for the selectivity. The method enables selective applications to pyrroloindoline targets and further refinement with chiral catalysts. (C) 2020 Elsevier Ltd. All rights reserved.

N-Trifluoromethyl Hydrazines, Indoles and Their Derivatives

Reported herein is the first efficient strategy to synthesize a broad range of unsymmetrical N-CF3 hydrazines, which served as platform to unlock numerous currently inaccessible derivatives, such as tri- and tetra-substituted N-CF3 hydrazines, hydrazones, sulfonyl hydrazines, and valuable N-CF3 indoles. These compounds proved to be remarkably robust, being compatible with acids, bases, and a wide range of synthetic manipulations. The feasibility of RN(CF3)-NH2 to function as a directing group in C-H functionalization is also showcased.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 601514-19-6. Quality Control of TWS119.

Efficient microwave-assisted diastereoselective synthesis of indole-based 4,5-dihydrofurans via a one-pot, three-component reaction in water

The combination of two or more different heterocyclic moieties in a single molecule would enhance biological activity significantly. The indole and furan scaffolds are promising candidates in drug design, and they have been widely found in natural products and therapeutic agents. Owing to their pharmaceutical importance, there is an urgent need to design rapid, efficient and environmentally benign protocols for the synthesis of indole-dihydrofuran biheterocycles. Herein, we have developed a novel ecofriendly approach for the diastereoselective synthesis of indole-based 4,5-dihydrofurans through a three-component reaction of 3-cyanoacetyl indoles with various aldehydes and N-phenacylpyridinium bromides in the presence of potassium carbonate as an inexpensive and non-toxic base in water under low power microwave irradiation. The findings show that aromatic and heteroaromatic aldehydes tolerated well in this reaction. The products were obtained in 85-98% yields in 4-20 min. The advantages of this method consist of the environmental friendly reaction conditions, use of green solvent and safe base, availability of raw materials, wide range of usable substrates, short reaction times, excellent yields and absence of any tedious workup or purification.

Quaternary stereocentres via catalytic enantioconvergent nucleophilic substitution reactions of tertiary alkyl halides

The development of efficient methods, particularly catalytic and enantioselective processes, for the construction of all-carbon quaternary stereocentres is an important (and difficult) challenge in organic synthesis due to the occurrence of this motif in a range of bioactive molecules. One conceptually straightforward and potentially versatile approach is the catalytic enantioconvergent substitution reaction of a readily available racemic tertiary alkyl electrophile by an organometallic nucleophile; however, examples of such processes are rare. Here we demonstrate that a nickel-based chiral catalyst achieves enantioconvergent couplings of a variety of tertiary electrophiles (cyclic and acyclic alpha-halocarbonyl compounds) with alkenylmetal nucleophiles to form quaternary stereocentres with good yield and enantioselectivity under mild conditions in the presence of a range of functional groups. These couplings, which probably proceed via a radical pathway, provide access to an array of useful families of organic compounds, including intermediates in the total synthesis of two natural products, (-)-eburnamonine and madindoline A.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 76-61-9, you can contact me at any time and look forward to more communication. Product Details of 76-61-9.
