Synthesis, structure and enantiomeric resolution of ferrocenylalkyl mercaptoazoles. Antitumor activity in vivo

Ferrocenylalkyl 2-mercaptobenzimidazoles 3 (a-e) and 2-mercaptobenzo[d]thiazole-2(3H)-thiones 5 (a-e) were prepared via the reaction of the alpha-(hydroxy)alkyl ferrocenes, FcCHR(OH) (1a-e; Fc = ferrocenyl; R = H, Me, Et, i-Pr, Ph), either with thiobenzimidazole in acetone at room temperature in the presence of TFA (catalytic amounts), in yields of 55-74%, or with thiobenzothiazole in methylendicloride in presence of aqueous HBF4 (equimolar amounts) at r.t.; in yields of 41-58%. The structures, electrochemical properties and enantiomeric resolution 3a-e and 5a-e (using HPLC on modified amylose as chiral selector) were investigated. In cyclic voltammetry all studied compounds exhibited a reversible one-electron oxidation-reduction wave owing to the ferrocene-ferricenium redox couple with a positive shift (0.56-0.80 V) compared with that of ferrocene (0.50 V). X-ray determinations of molecular structures of 3-ferrocenylmethylbenzo[d]thiazole-2(3H)-thione (5a) 3-ferrocenylethylbenzo[d]thiazole-2(3H)-thione (5b) and 3-ferrocenylphenylmethylbenzo[d]thiazole-2(3H)-thione (5d) were carried out. The toxicity and antitumor activity of N-(ferrocenylethyl)-2-thiobenzimidazole (3b) were evaluated in vivo. Maximum tolerated dose (MTD) value for the compound 3b was found to be equal to 800 mg kg-1. The effectiveness of compound under investigation against murine solid tumor system, carcinoma Ca755 (Ca755), was studied in a wide range of doses and significant antitumor effects were found. The index of tumor growth inhibition (TGI) on Ca755 equaled 87% in comparison with control.

Synthesis of [N,P] ligands based on pyrrole. Application to the total synthesis of arnottin i

This paper describes the synthesis of a new class of [N,P] ligands based on pyrrole with a dimethylamino group as hard donor and a phosphine moiety as soft base. We have also modified the phosphine fragment to change the electronic and steric properties of these ligands. Palladium complex 3a proved to be very efficient in Heck cross-coupling reactions and in intramolecular aryl-aryl couplings of esters and amides. We have demonstrated the applicability and efficiency of this novel catalyst in the total synthesis of the natural product arnottin I.

Synthesis and electrochemical properties of 1,1?-bis (benzo-1,3-dithiol-2-ylidene)ferrocene derivatives as novel electron donor compounds

A number of 1,1?-bis(benzo-1,3-dithiol-2-ylidene)ferrocene derivatives 7a-b and 12-14 based on the strong electron donating ability of 1,3-dithiole and ferrocene moieties were synthesized as new pi-donors. The structure and physical properties of these compounds were characterized both by experimental techniques and spectral analysis. These new classes of donor compounds were obtained in very high yields based on modification of the Wittig-Horner reaction and the 1,3-dithiole rings were separated by conjugated spacers including aryl-ferrocenyl- aryl. The electrochemical properties of the new compounds have been studied in comparison to DB-TTF 4 analogues, and the parent ferrocene donor by cyclic voltammetry (CV), using Pt electrode as the working electrode in CH2Cl2 solutions at room temperature. Three subsequent oxidation processes are observed as three oxidation waves associated only with two reduction processes.

Diamond Phase (sp3-C) Rich Boron-Doped Carbon Nanowalls (sp2-C): Physicochemical and Electrochemical Properties

The growth of B-CNW with different boron doping levels controlled by the [B]/[C] ratio in plasma, and the influence of boron on the obtained material’s structure, surface morphology, electrical properties, and electrochemical parameters, such as -DeltaE and k, were investigated. The fabricated boron-doped carbon nanowalls exhibit activity toward ferricyanide redox couple, reaching the peak separation value of only 85 mV. The flatband potential and the concentration of boron carriers were estimated in the B-CNW samples using the Mott-Schottky relationship. It was shown that the vertically oriented carbon planes are characterized by p-type conductivity and very high hole-acceptor concentration (3.33 ¡Á 1023 cm-3 for a highly doped sample), which provides high electrical conductivity. The enhanced electrochemical performance of B-CNWs electrodes is an advantageous feature that can be applied in ultrasensitive detection or energy storage devices. (Graph Presented).

Tricoordinate Coinage Metal Complexes with a Redox-Active Tris-(Ferrocenyl)triazine Backbone Feature Triazine?Metal Interactions

2,4,6-Tris(1-diphenylphosphanyl-1?-ferrocenylene)-1,3,5-triazine (1) coordinates all three coinage metal(I) ions in a 1:1 tridentate coordination mode. The C3-symmetric coordination in both solid state and solution is stabilised by an uncommon cation?pi interaction between the triazine core and the metal cation. Intramolecular dynamic behaviour was observed by variable-temperature NMR spectroscopy. The borane adduct of 1, 1BH3, displays four accessible oxidation states, suggesting complexes of 1 to be intriguing candidates for redox-switchable catalysis. Complexes 1Cu, 1Ag, and 1Au display a more complicated electrochemical behaviour, and the electrochemical mechanism was studied by temperature-resolved UV/Vis spectroelectrochemistry and chemical oxidation.

Simultaneous arrangement of up to three different molecules on the pore surface of a metal-macrocycle framework: Cooperation and competition

Porous crystals are excellent materials with potential spatial functions through molecular encapsulation within the pores. Co-encapsulation of multiple different molecules further expands their usability and designability. Herein we report the simultaneous arrangement of up to three different guest molecules, TTF (tetrathiafulvalene), ferrocene, and fluorene, on the pore surfaces of a porous crystalline metal-macrocycle framework (MMF). The position and orientation of adsorbed molecules arranged in the pore were determined by single-crystal X-ray diffraction analysis. The anchoring effect of hydrogen bonds between the hydroxy groups of the guest molecules and inter-guest cooperation and competition are significant factors in the adsorption behaviors of the guest molecules. This finding would serve as a design basis of multicomponent functionalized nanospaces for elaborate reactions that are realized in enzymes.

Electrochemical anion recognition with ferrocene functionalised macrocycles

The syntheses and characterization of two new redox active cyclam ligands ferrocenylmethyl-(6-methyl-1,4,8,11tetraazacyclotetradec-6-y1)-amine (L3) and 1,1′-ferrocenylmethyl-bis(6-methyl-1,4,8,11-tetraazacyclotetradec-6-yl)-amine (L4) are reported. The compounds each possess a ferrocenyl group bearing one (L3) or two (L4) appended macrocycles linked by their exocyclic amino groups and the crystal structures of both compounds have been determined. Anion binding of L3 and L4 was investigated by electrochemical titrations where H-bonding to each macrocycle causing a shift in the Fc+/0 redox potential was used as a reporter of guest binding. The ZnII complex of L3 has also been isolated and characterized structurally. These compounds were analysed for their capacity to electrochemically recognize anions in both aqueous and non-aqueous solution, We have found that L3, L4 and [ZnL 3]2+ sense Cl- and AcO- anions in MeCN-CH2Cl2, a function that is lost in aqueous solution.

Catalytic Oxo/Imido Heterometathesis by a Well-Defined Silica-Supported Titanium Imido Complex

Grafting Ti(=NtBu)(Me2Pyr)2(py)2 (Me2Pyr= 2,5-dimethylpyrrolyl, py=pyridine) onto the surface of silica partially dehydroxylated at 700 C gives the well-defined silica-supported Ti imido complex (?SiO)Ti(=NtBu)(Me2Pyr)(py)2, which is fully characterized by IR and solid-state NMR spectroscopy as well as elemental and mass balance analyses. While stoichiometric imido-transfer reactivity is typical for Ti imides, the obtained surface complex is unique in that it enables catalytic transformations involving Ti imido and oxo intermediates. In particular, it efficiently catalyzes imidation of carbonyl compounds with N-sulfinylamines by oxo/imido heterometathesis.
