Ferrocenylvinyl-flavones: Synthesis, structure, anticancer and antibacterial activity studies

Four new ferrocenyl-flavone complexes were obtained via palladium-catalyzed Heck cross-coupling reactions; (E)-6-ferrocenylvinyl-chromen-4-one (4), (E)-6-ferrocenylvinyl-2-methyl-chromen-4-one (5), (E)-6-ferrocenylvinyl-2- phenyl-chromen-4-one (6) and (E)-6-ferrocenylvinyl-chromen-4-one-3-propionic acid (7). All compounds were characterized by 1H NMR, 13C NMR, IR spectroscopy, high resolution-MS, elemental analysis and cyclic voltammetry. The molecular structure of derivatives 4 and 6 was also confirmed by X-ray crystallography. The biological activity of the complexes was rationalized on the basis of their anticancer and antibacterial properties. The anticancer activity of ferrocenyl-flavones 4 e7 against established human cell lines derived from hematological and solid tumors has been evaluatedin vitro. The following cell lines were investigated: MCF-7 (estrogen receptor-responsive breast adenocarcinoma), MDA-MB-231 (estrogen receptor-negative breast adenocarcinoma), HepG2 (hepatocellular carcinoma) and CCRF-CEM (T lymphoblast-like polymorph cells). All investigated ferrocenyl-flavones show cytotoxicity against CCRF-CEM cell line. The antibacterial activity of the four ferrocenyl-flavones against Gram-positive methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), vancomycin-resistant S. aureus (VRSA) and Staphylococcus epidermidis bacterial strains was determined. Our experiments show antibacterial activity for the carboxylic acid derivative 7 against all tested Gram-positive bacterial strains while no activity was detected for the ferrocene-free 6-bromo-chromen-4-one-3-propionic acid.

Synthesis of alpha-arylalkylferrocenes through cesium fluoride-promoted coupling of arylboronic acids with N-tosylhydrazones

A cesium fluoride-promoted reductive coupling reaction of acylferrocene tosylhydrazones with arylboronic acids has been developed, producing highly substituted alpha-arylalkylferrocenes in moderate to excellent yields. The reaction employs anionic fluorine to facilitate the cleavage of C?B bond. The developed methodology demonstrates a wide substrate scope and high functional groups tolerance. Moreover, the alpha-arylalkylferrocenes compounds were also obtained on a multi-gram scale.

Metal-catalyzed electrochemical diazidation of alkenes

Vicinal diamines are a common structural motif in bioactive natural products, therapeutic agents, and molecular catalysts, motivating the continuing development of efficient, selective, and sustainable technologies for their preparation. We report an operationally simple and environmentally friendly protocol that converts alkenes and sodium azide?both readily available feedstocks?to 1,2-diazides. Powered by electricity and catalyzed by Earth-abundant manganese, this transformation proceeds under mild conditions and exhibits exceptional substrate generality and functional group compatibility. Using standard protocols, the resultant 1,2-diazides can be smoothly reduced to vicinal diamines in a single step, with high chemoselectivity. Mechanistic studies are consistent with metal-mediated azidyl radical transfer as the predominant pathway, enabling dual carbon-nitrogen bond formation.

Modellreaktionen zur Umsetzung von Ferrocen-1,1′-dithiol mit Diolefinen:II. Die Saeuren- und Basenkatalysierten Reaktionen von Ferrocenthiolen mit aktivierten Olefinen

Both ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, add to activated olefins to give 1:1 and 1:2 adducts, respectively.The base-catalysed (NEt3) reactions of the monofunctional ferrocenethiol with the mono-olefins methyl methacrylate, methyl vinyl sulfone and benzylidene acetone lead to expected 1:1 adducts whereas 2:1 adducts are obtained with bifunctional olefins such as divinyl sulfone and dibenzylidene acetone.The corresponding bifunctional ferrocene-1,1′-dithiol gives 1:2 adducts with methyl methacrylate, methyl vinyl ketone and benzylidene acetone.For comparison, the aliphatic 2-ferrocenyl-ethanethiol, Fe(C5H5)(C5H4-CH2CH2SH), was reacted with methyl vinyl sulfone and divinyl sulfone.In all cases, the disulfides Fc-SS-Fc and Fc-CH2CH2-SS-CH2CH2-Fc, respectively, are also formed.The acid-catalysed (HCl) reactions of ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, with isobutyl vinyl ether produce the expected 1:1 and 1:2 adducts although the formation of dimercaptals is also possible.Thus the reaction of ferrocene-1,1′-dithiol with isobutyl vinyl ether leads to both the 1:2 adduct and the 2-methyl 1,3-dithia-<3>ferrocenophane, Fe(C5H4S)2CH(CH3), and the HCl-catalysed addition of ferrocenethiol to 1,4-butadienol divinyl ether gives 1,1-di(ferrocenylmercapto) ethane, CH3CH(SFc)2.The new sulfur derivatives of ferrocene were characterized by 1H and 13C NMR spectroscopy.Keywords: Iron; Ferrocene; Ferrocene thiol; Addition to olefins; NMR

Charge-Transfer Diffusion Rates and Activity Relationships during Oxidation and Reduction of Plasma-Polymerized Vinylferrocene Films

Ferrocene and ferrocenium sites in radiofrequency plasma polymer films on Pt electrodes can be electrochemically oxidized and re-reduced in contact with a variety of electrolyte/solvent systems.When the electrochemical reaction is conducted under near-equilibrium conditions, cyclic voltammetric and chronopotentiometric waveshapes reflect the modulation of ferrocene and ferrocenium site activities by solvent swelling of the film.In water, ferrocene sites exhibit a phase-like (constant) activity during film oxidation, but in acetonitrile ferrocene site activity is proportional to fractional film oxidation.When the film oxidation or reduction is driven by a large potential step (avoiding film ohmic resistance effects), the rate of film reaction is controlled by Fickian diffusion of electrochemical charge through the film.In water, the product of charge diffusion constant and initial concentration of electroactive sites, D1/2C, is 2 X 10-8 mol/cm2 s1/2 for film oxidation and 1.4 X 10-8 mol/cm2 s1/2 for film re-reduction.The difference may be due greater film swelling in the oxidized state.The relationship of charge diffusion rates in redox polymer films on electrodes to their electrocatalytic reactions is discussed.

Synthetic Diversity from a Versatile and Radical Nitrating Reagent

We leverage the slow liberation of nitrogen dioxide from a newly discovered, inexpensive succinimide-derived reagent to allow for the C?H diversification of alkenes and alkynes. Beyond furnishing a library of aryl beta-nitroalkenes, this reagent provides unparalleled access to beta-nitrohydrins and beta-nitroethers. Detailed mechanistic studies strongly suggest that a mesolytic N?N bond fragmentation liberates a nitryl radical. Using in situ photo-sensitized, electron paramagnetic resonance spectroscopy, we observed direct evidence of a nitryl radical in solution by nitrone spin-trapping. To further exhibit versatility of N-nitrosuccinimide under photoredox conditions, the late-stage diversification of an extensive number of C?H partners to prepare isoxazolines and isoxazoles is presented. This approach allows for the formation of an in situ nitrile oxide from a ketone partner, the presence of which is detected by the formation of the corresponding furoxan when conducted in the absence of a dipolarophile. This 1,3-dipolar cycloaddition with nitrile oxides and alkenes or alkynes proceeds in a single-operational step using a mild, regioselective, and general protocol with broad chemoselectivity.
