Collision-induced dissociation of protonated fentanyl: A DFT study

The fragmentation pathways leading to the major products resulting from collision-induced dissociation of protonated fentanyl are investigated. Starting from a protonated fentanyl in a twist conformation, transfer of the proton from the piperidine to the amide nitrogen allows the lone pair of the piperidine nitrogen to assist in displacement of the amide group and results in ring-opening of the piperidine to yield an ion with m/z 188 (C13H18N+). This is the fragmentation pathway with the lowest energy barrier; the barrier to the loss of the phenethyl group as a phenonium or 1-phenylethyl cation from the nitrogen in the piperidine ring is 64 kJ mol(-1) higher in energy. At even higher collision energies a bicyclic ion, also with nominal m/z 188 but with different elemental composition (C12H14NO+), is formed after sequential losses of ethene and phenethylamine from protonated fentanyl. Possible pathways to ring opening of the piperidine ring of N-protonated fentanyl include nucleophilic attack by the amide oxygen or the phenyl ring on the piperidine ring. The two m/z 188 ions give different dissociation products; minor products in the mass spectrum of protonated fentanyl at m/z 146, 134 and 132 are all generated from the dominant m/z 188 ion, C13H18N+, whereas only a product at m/z 132 is formed from the C12H14NO+ ion.

Cationic Bismuth Aminotroponiminates: Charge Controls Redox Properties

The behavior of the redox-active aminotroponiminate (ATI) ligand in the coordination sphere of bismuth has been investigated in neutral and cationic compounds, [Bi(ATI)(3)] and [Bi(ATI)(2)L-n][A] (L=neutral ligand; n=0, 1; A=counteranion). Their coordination chemistry in solution and in the solid state has been analyzed through (variable-temperature) NMR spectroscopy, line-shape analysis, and single-crystal X-ray diffraction analyses, and their Lewis acidity has been evaluated by using the Gutmann-Beckett method (and modifications thereof). Cyclic voltammetry, in combination with DFT calculations, indicates that switching between ligand- and metal-centered redox events is possible by altering the charge of the compounds from 0 in neutral species to +1 in cationic compounds. This adds important facets to the rich redox chemistry of ATIs and to the redox chemistry of bismuth compounds, which is, so far, largely unexplored.

Homochiral versus Heterochiral Trifluoromethylated Pseudoproline Containing Dipeptides: A Powerful Tool to Switch the Prolyl-Amide Bond Conformation

The design of constrained peptides is of prime importance in the development of bioactive compounds and for applications in supramolecular chemistry. Due to its nature, the peptide bond undergoes a spontaneous cis-trans isomerism, and the cis isomers are much more difficult to stabilize than the trans forms. By using oxazolidine-based pseudoprolines (psi Pro) substituted by a trifluoromethyl group, we show that the cis peptide bond can be readily switched from 0% to 100% in Xaa-psi Pro dipeptides. Our results prove that changing the configuration of the C-alpha in Xaa or in psi Pro is sufficient to invert the cis:trans populations while changing the nature of the Xaa side chain finely tuned the conformers ratio. Moreover, a strong correlation is found between the puckering of the oxazolidine ring and the peptide bond conformation. This finding highlights the role of the trifluoromethyl group in the stabilization of the peptide bond geometry. We anticipate that such templates will be very useful to constrain the backbone geometry of longer peptides.

Thermally stable, solution processable and redox active new poly(amide-imide)s: synthesis and characterization

A series of new poly(amide-imide)s was prepared by polycondensation of our already reported diamine, N,N’-[((propane-2,2-diylbis(4,1-phenylene) bis(oxy))bis(4,1-phenylene)]bis(4-aminobenzamide) (BDM) containing flexible ether and amide linkages with different aromatic dianhydrides via simple two-step method. The synthesized poly(amide-imide)s were characterized by FTIR spectroscopy and elemental analysis. These poly(amide-imide)s demonstrated nice solubility in most of the organic solvents at ambient temperature and upon heating. They also revealed great thermal stability and showed glass transition temperatures (Tgs) exceeding 150 degrees C in addition to the temperature of 10% weight loss (T-10) that fluctuated from 460 to 522 degrees C having more than 59% residual yield at 800 degrees C in nitrogen atmosphere indicating their flame retardant characteristics. Furthermore, they also showed interesting photoluminescent properties with blue green solution emission properties, redox activity, and lower onset oxidation potentials with appreciably shallow HOMO levels.

The reaction of N-alkyl-2,N-dilithiobenzothioamides, generated by treating N-alkylbenzothioamides with two equivalents of butyllithium, with aldehydes gives the corresponding 2-(1-hydroxyalkyl)benzothioamides, which undergo cyclization on treatment with methanesulfonyl chloride in the presence of triethylamine to yield 3,N-disubstituted (Z)-benzo[c]thiophen-1(3H)-imines. 2,3-Disubstituted 2,3-dihydro-1H-isoindole-1-thiones are obtained by the reaction of the above hydroxy thioamides with two equivalents of sodium hydride followed by an equivalent of phenyl chloroformate.

Removal of tetracycline from aqueous solution using Fe-doped zeolite

Tetracycline is one of the most widely used antibiotics that causes contamination of aqueous environments and has raised serious concern during the past few years. In this work, adsorption of tetracycline on a modified zeolite was studied through a batch system. Synthetic zeolite 13X was modified using Fe(III). The results show that the removal efficiency of tetracycline by modified zeolite has considerably increased. Different experiments were carried out in order to analyze the effect of parameters such as pH, initial concentration of tetracycline, time, etc. The results indicate that tetracycline adsorption on the zeolite strongly depends on the pH of the solution due to amphoteric functional groups of tetracycline and maximum adsorption capacity of tetracycline by modified zeolite with a pH of approximately 6. The Langmuir isotherm shows good agreement with the experimental data suggesting monolayer adsorption. Maximum adsorption capacity of the modified zeolite reached at the experiments is almost 200 mg/g. XRD, XRF and FTIR results confirm the existence of the Fe phase in the zeolite texture. Amide groups of TC were responsible for the complexation with Fe3+. Also, tetracycline removal was studied in a continuous column to simulate an industrial waste water process.

Palladium/copper-catalyzed multicomponent reactions of propargylic amides, halohydrocarbons and CO2 toward functionalized oxazolidine-2,4-diones

A palladium/copper-catalyzed oxy-carbonation of propargylic amides by halohydrocarbons and CO2 has been developed toward functionalized oxazolidine-2,4-diones. This multi-component reaction (MCR) was triggered by the oxidative addition of RX to Pd(0), followed by the sequential carboxylation of amide and trans-oxopalladation of an electron-deficient triple bond by RPdX species. Finally, the reductive elimination afforded products possessing tetra-substituted vinyl motifs and Pd(0). This protocol features simultaneous formation of three bonds, representing an efficient method for incorporation of CO2 into value-added heterocycles.

Iridium-Catalyzed Regio- and Enantioselective Borylation of Unbiased Methylene C(sp(3))-H Bonds at the Position beta to a Nitrogen Center

Reported herein is the pyrazole-directed iridium-catalyzed enantioselective borylation of unbiased methylene C-H bonds at the position beta to a nitrogen center. The combination of a chiral bidentate boryl ligand, iridium precursor, and pyrazole directing group was responsible for the high regio- and enantioselectivity observed. The method tolerated a vast array of functional groups to afford the corresponding C(sp(3))-H functionalization products with good to excellent enantioselectivity.

Oxaziridine cleavage with a low-valent nickel complex: competing C-O and C-N fragmentation from oxazanickela(II)cyclobutanes

Reacting the low-valent nickel complex [(dtbpe)Ni](2)(mu-eta(2): eta(2)-C6H6) with oxaziridines was found to form mixtures of imine, amide and aldehyde products. If the N-substituent of the oxaziridine is sufficiently bulky, a short-lived intermediate can be isolated and characterized by X-ray diffraction studies as an oxazanickela(II) cyclobutane. This is the first well-defined example of N-O oxidative addition of an oxaziridine to a transition metal. Subsequent fragmentation of this oxazanickelacyclobutane forms a complex mixture of products, including a nickel(II) imido complex, demonstrating that oxaziridines can serve as nitrene precursors. Preliminary mechanistic analysis is consistent with a bimetallic mechanism of fragmentation of the oxazanickelacyclobutane to form the nickel imido and eta(2)-aldehyde complexes.

Visible-Light-Enabled Oxidative Coupling of Alkenes with Dialkylformamides To Access Unsaturated Amides

A practical and direct method for oxidative cross-coupling of alkenes with dialkylformamides is established employing visible-light-enabled photoredox catalysis. This strategy allows efficient access to diverse unsaturated amides under mild reaction conditions. The application of an appropriate diaryliodonium salt was demonstrated to be critical to the success of this process. This catalyst system is well tolerant of a variety of useful functional groups.
