One-Pot Reactions Involving the Fischer Indole Synthesis and Friedel-Crafts Reactions

A series of compounds have been prepared by the Fischer indole synthesis and Friedel-Crafts reactions, using a single acid catalyst in a one-pot conversion. The reactions have worked best with pyridyl-substituted hydrazones/indoles. Chlorination and bromination products are formed in good yields and high regioselectivities. Acylation products have also been prepared by the two-stage reaction. In the case of alkylation, the expected alkyl-substituted indoles are obtained however they are accompanied by over-alkylation products.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2447-57-6 is helpful to your research. Computed Properties of C12H14N4O4S.

Gold-catalyzed enantioselective functionalization of indoles

Gold catalysis and indole chemistry are two mature and prolific fields. The gold-catalyzed functionalization of indoles has produced numerous results and paved the way for novel strategies in the building of molecular complexity. However – and curiously – though enantioselective gold catalysis is now a well-established field, it has been relatively little applied to the modification of indoles. This review highlights most of the enantioselective gold-catalyzed examples of the functionalization of indoles in order to emphasize the strengths and limitations of the method.

Rhodium-Catalyzed C-H Functionalization of N-(2-Pyrimidyl) indole with Internal Alkynes: Formation of Unexpected Products by Regulating the Amount of Silver Acetate

Herein we disclose an uncommon Rhodium(III)-catalyzed C2-selective functionalization of N-(2-Pyrimidyl)indole with internal alkynes. Excess amounts of silver acetate (5.0 equiv.) were found to be crucial for the efficient C2 naphthylation and C2 enol esterification of indoles. In sharp contrast, 2.0 equivalents of silver acetate resulted in the C-H alkenylation only. Control experiments were also carried out to briefly study the mechanism of this transformation.

Microbiota-Derived Metabolites, Indole-3-aldehyde and Indole-3-acetic Acid, Differentially Modulate Innate Cytokines and Stromal Remodeling Processes Associated with Autoimmune Arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the synovial joints. Inflammation, new blood vessel formation (angiogenesis) and bone resorption (osteoclastogenesis) are three key processes involved in the joint damage and deformities of arthritis. Various gut microbiota-derived metabolites are implicated in RA pathogenesis. However, there is barely any information about the impact of two such metabolites, indole-3-aldehyde (IAld) and indole-3-acetic acid (I3AA), on arthritis-related processes. We conducted a comparative analysis of IAld and I3AA using established cell-based models to understand how they might influence RA pathogenesis. Although structurally similar, the bioactivities of these two metabolites were profoundly different. IAld but not I3AA, inhibited the expression of pro-inflammatory cytokines (IL-1 beta and IL-6) in RAW 264.7 (RAW) cells stimulated with heat-killed M. tuberculosis sonicate (Mtb) and lipopolysaccharide (LPS). IAld also exhibited pro-angiogenic activity and pro-osteoclastogenic activity. In contrast, I3AA exhibited anti-angiogenic activity on endothelial cell tube formation but had no effect on osteoclastogenesis. Both IAld and I3AA have been proposed as aryl hydrocarbon receptor (AhR) agonists. Use of CH-223191, an inhibitor of the AhR, suppressed the anti-angiogenic activity of I3AA but failed to mitigate the effects of IAld. Further investigation of the anti-inflammatory activities of IAld and I3AA in LPS-treated RAW cells indicated that inhibition of MyD88-dependent activation of NF-kappa B and MAPK pathways was not likely involved. Our results suggest that the relative bioavailability of these indole derivatives may differentially impact RA progression and possibly other diseases that share similar cellular processes.

Generation of lndoles with Agrochemical Significance through Biotransformation by Chaetomium globosum

Six new (1-6) and two known (7 and 8) indole alkaloids were produced by the marine fish-derived fungus Chaetomium globosum ICSI through biotransformation. The structures of these alkaloids were elucidated by a combination of MS, NMR, and X-ray crystallography analyses. Chaetoindolone A (1) was shown to inhibit the growth of the rice-pathogenic bacteria Xanthomonas oryzae pv. oryzae (xoo) both in vitro and in vivo. Chaetogline A (7) was found to be fungicidal against Sclerotinia sclerotiorum, a pathogen causing rape sclerotinia rot. Collectively, this work provides access to new indole alkaloids with potential agrochemical significance.

Total synthesis of kopsine, fruticosine, and structurally related polycyclic caged Kopsia indole alkaloids

Kopsine, fruticosine and related caged and polycyclic Kopsia indole alkaloids have been attractive synthetic targets since 1983. Besides their promising bioactivities, the multiple continuous stereogenetic centers including two all-carbon quaternary stereocenters embedded in a rigid and caged polycyclic skeleton poses significant challenges in synthetic chemistry. Due to the extrodinary complex structures, tremendous efforts have been devoted to these synthetic targets. In this review, we discuss reported strategies for the total synthesis of kopsine, fruticosine and related Kopsia indole alkaloids with an emphasis on tactics to construct the polycyclic skeleton and methodologies to install the C7/C20 stereocenters.
