Oxidative organocatalytic chemoselective N-acylation of heterocycles with aromatic and conjugated aldehydes

Selective acylation of indoles is cumbersome often involving the need for sensitive and reactive acyl chloride derivatives or coupling reagents. Here we report a mild, functional group tolerant and highly chemoselective oxidative carbene catalyzed N-acylation of indoles with aldehydes. The acylation has a broad substrate scope and is compatible with substituents on both the aldehyde and the indole reaction partner. Furthermore, aza-heterocycles such as pyrrole and indazole can also be used as nucleophiles in this reaction providing the corresponding amide congeners in good yield.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 39011-92-2, you can contact me at any time and look forward to more communication. HPLC of Formula: C12H22O2.

Recyclable CuFe2O4 for the synthesis of 2,3-disubstituted indoles

A method for the CuFe2O4-catalyzed coupling of 2-iodo- or 2-bromoanilines and acetylacetone or isosteric 1,3-diketones to afford 2,3-disubstituted indoles has been developed. The superparamagnetic material showed superior activity in comparison to other ferrites or copper-based metal-organic frameworks. Functionalities including ester, cyano, and halogen groups were compatible with the reaction conditions. The CuFe2O4 catalyst was easily recoverable and reusable and offers a convenient pathway to afford synthetically useful heterocycles. (C) 2020 Elsevier Ltd. All rights reserved.

Is naphthylphthalamic acid a specific phytotropin? It elevates ethylene and alters metabolic homeostasis in tomato

In higher plants, phytohormone indole-3-acetic acid is characteristically transported from the apex towards the base of the plant, termed as polar auxin transport (PAT). Among the inhibitors blocking PAT, N-1-naphthylphthalamic acid (NPA) that targets ABCB transporters is most commonly used. NPA-treated light-grown Arabidopsis seedlings show severe inhibition of hypocotyl and root elongation. In light-grown tomato seedlings, NPA inhibited root growth, but contrary to Arabidopsis stimulated hypocotyl elongation. The NPA-stimulation of hypocotyl elongation was milder in blue, red, and far-red light-grown seedlings. The NPA-treatment stimulated emission of ethylene from the seedlings. The scrubbing of ethylene by mercuric perchlorate reduced NPA-stimulated hypocotyl elongation. NPA action on hypocotyl elongation was antagonized by 1-methylcyclopropene, an inhibitor of ethylene action. NPA-treated seedlings had reduced levels of indole-3-butyric acid and higher levels of zeatin in the shoots. NPA did not alter indole-3-acetic levels in shoots. The analysis of metabolic networks indicated that NPA-treatment induced moderate shifts in the networks compared to exogenous ethylene that induced a drastic shift in metabolic networks. Our results indicate that in addition to ethylene, NPA-stimulated hypocotyl elongation in tomato may also involve zeatin and indole-3- butyric acid. Our results indicate that NPA-mediated physiological responses may vary in a species-specific fashion.

Alkyl indole-based cannabinoid type 2 receptor tools: Exploration of linker and fluorophore attachment

Cannabinoid type 2 (CB2) receptor continues to emerge as a promising drug target for many diseases and conditions. New tools for studying CB2 receptor are required to further inform how this receptor functions in healthy and diseased states. The alkyl indole scaffold is a well-recognised ligand for cannabinoid receptors, and in this study the indole C5-7 positions were explored for linker and fluorophore attachment. A new high affinity, CB2 receptor selective inverse agonist was identified (16b) along with a general trend of C5-substituted indoles acting as agonists versus C7-substituted indoles acting as inverse agonists. The indole C7 position was found to be the most tolerant to linker extension and resulted in a high affinity inverse agonist with a medium length linker (19). Although a high affinity fluorescent ligand for CB2 receptor was not identified in this study, the indole C7 position shows great promise for fluorophore or probe attachment.

Annulation Cascades of N-Allyl-N-((2-bromoaryl)ethynyl)amides Involving C-H Functionalization

An annulation cascades of N-allyl-N-((2-bromoaryl)ethynyl)amides with terminal alkynes or 1,3-dicarbonyls involving C-H functionalization for producing 2,3-functionalized indoles has been first developed by means of Cu catalysis. The method is enabled by the formation of the ketenimine intermediates to deliver 2,3-disubstituted indoles through a sequence of aza-Claisen rearrangement, C-H functionalization, Ullmann C-N coupling, and cyclization.

Identification of an aldehyde oxidase involved in indole-3-acetic acid synthesis in Bombyx mori silk gland

Auxin is thought to be an important factor in the induction of galls by galling insects. We have previously shown that both galling and nongalling insects synthesize indole-3-acetic acid (IAA) from tryptophan (Trp) via two intermediates, indole-3-acetaldoxime (IAOx) and indole-3-acetaldehyde (IAAld). In this study, we isolated an enzyme that catalyzes the last step IAAld -> IAA from a silk-gland extract of Bombyx mori. The enzyme, designated BmIAO1, contains two 2Fe-2S iron-sulfur-cluster-binding domains, an FAD-binding domain, and a molybdopterin-binding domain, which are conserved in aldehyde oxidases. BmIAO1 causes the nonenzymatic conversion of Trp to IAAld and the enzymatic conversion of IAOx to IAA, suggesting that BmIAO1 alone is responsible for IAA production in B. mori. However, a detailed comparison of pure BmIAO1 and the crude silk-gland extract suggested the presence of other enzymes involved in IAA production from Trp.

Supramolecular self-assemblies of engineered polyethylenimines as multifunctional nanostructures for DNA transportation with excellent antimicrobial activity

In this study, indole-3-butanoic acid (IBA), a biologically and environmentally safe entity, has been grafted onto low and high molecular weight (1.8 and 25 kDa) polyethylenimines (PEI) mainly through primary amines to obtain amphiphilic indole-3-butanoyl-polyethylenimines (IBPs). Two series of IBPs (IBP1.8 and IBP25) were prepared which, on self-assembly in aqueous medium, yielded multifunctional nanomicellar structures (IBP1.8 and IBP25) capable of transporting genetic material in vitro and exhibiting other biological activities. Physicochemical characterization showed the size of IBP1.8 and IBP25 nanostructures in the range of similar to 332-234 nm and similar to 283-166 nm, respectively, with zeta potential varying from similar to+29-17 mV and similar to+37-25 mV. DNA release assay demonstrated higher release of plasmid DNA from IBP nanostructures as compared to native PEIs. Cytotoxicity showed a decreasing pattern with increasing degree of grafting of IBA onto PEIs making these nanostructures non-toxic. pDNA complexes of these nanostructures (both IBPs(1.8) and IBPs(25)) displayed considerably higher transfection efficiency, however, IBP1.8/pDNA complexes performed much better (similar to 7-9 folds) as compared to native PEI/pDNA and Lipofectamine/pDNA complexes on mammalian cells. CLSM analysis revealed that these complexes entered nucleus in sufficient amounts suggesting higher uptake and efficient internalization of the complexes. Besides, these supramolecular nanostructures not only exhibited excellent antimicrobial potential (MIC similar to 49-100 mu g/ml) against clinical as well as resistant pathogenic strains but also found to possess antioxidant property. Overall, the projected low molecular weight PEI-based vectors could serve as more effective multifunctional nanomaterials having promising potential for future gene therapy applications with capability to provide protection against other bacterial infections.

Acceptorless dehydrogenative condensation: synthesis of indoles and quinolines from diols and anilines

The use of diols and anilines as reagents for the preparation of indoles represents a challenge in organic synthesis. By means of acceptorless dehydrogenative condensation, heterocycles, such as indoles, can be obtained. Herein we present an experimental and theoretical study for this purpose employing heterogeneous catalysts Pt/Al2O3 and ZnO in combination with an acid catalyst (p-TSA) and NMP as solvent. Under our optimized conditions, the diol excess has been reduced down to 2 equivalents. This represents a major advance, and allows the use of other diols. 2,3-Butanediol or 1,2-cyclohexanediol has been employed affording 2,3-dimethyl indoles and tetrahydrocarbazoles. In addition, 1,3-propanediol has been employed to prepare quinolines or natural and synthetic julolidines.
