The selective hydrogenation of the nitro moiety is a difficult task in the presence of other reducible functional groups such as alkenes or alkynes. We show that the carbon-based (metal-free) catalyst can be used to selectively reduce substituted nitro groups using H-2 as a reducing agent, providing a great potential to replace noble-metal catalysts and contributing to simple and greener strategies for organic synthesis.

The rearrangement of ene-aldimines is a useful reaction for affording homoallylic amines. Despite their utilities in synthetic chemistry, the rearrangement for accessing homoallylic amines substituted at the 2-position remains elusive. In this study, the Bronsted acid-initiated formal [1,3]-rearrangement of ene-aldimines was developed to synthesize 2,4,4-substituted homoallylic amines that were otherwise inaccessible previously. Our study reveals an intermolecular pathway in which the rearrangement proceeds via a protonation-mediated 2-azaallenium cation.

A group of new polyimides (PIs) containing xanthene bulky groups and heterocyclic pyridine ring were synthesized by polycondensation reaction by using new symmetric and asymmetric diamines with available dianhydrides. The prepared diamines and PIs were characterized by Fourier transform infrared, elemental analysis, and proton nuclear magnetic resonance spectroscopy and carbon nuclear magnetic resonance spectroscopy. The PIs have desirable solubility in common aprotic solvents like dimethyl sulfoxide, N-methyl-2-pyrrolidone, dimethylacetamide, and pyridine as a less polar solvent. The PIs with inherent viscosities in the range of 0.51-0.72 dL/g were amorphous in nature, showed glass transition temperatures (T(g)s) of about 270-300 degrees C, and 10% weight loss at temperatures 384-443 degrees C. They showed fluorescence emission (quantum yield 7-12%) due to the presence of xanthene and pyridine groups in their structure. The prepared PIs showed tensile strength of 81-91 MPa with elongation at break of 19-23%. The antibacterial properties of the PIs against Gram negative and Gram positive bacteria and funguses were investigated. Also, a membrane of PI prepared by electrospinning method was used for the removal of different concentrations of Cr(VI) from aqueous solutions.

A new photoactive Pt (II) hydroxyquinoline complex has been covalently linked into the structure of an iminebased layered covalent organic framework (COF) through the monomer truncation strategy. Such strategy allows the incorporation of molecular fragments with only one functional group able to condensate into the imine-framework. The photocatalytic activity of the resulting Pt@COF has been applied to the oxidation of sulfides to sulfoxides, obtaining excellent results for all the studied cases, and showing that this reaction goes through both photoredox and energy transfer processes. The results obtained showed a great enhancement of the catalytic activity (up to 25,000 turnover number, TON), stability and a significant decrease on the reaction times, as a consequence of immobilization and isolation of Pt(II) centers into the organic framework. In addition, Pt@COF has been proved to be an excellent heterogeneous photocatalyst also in exclusive photoredox processes, reaching 7500 TON in hydrodebromination reactions.

Six new derivatives of ciprofloxacin compounds and their copper(II) complexes were synthesized, characterized by spectroscopic methods (ultraviolet-visible [UV-vis], Fourier transform infrared [FTIR], nuclear magnetic resonance [NMR], mass spectrometry [MS], and electron paramagnetic resonance [EPR]), and tested for antibacterial activities against gram-negative and gram-positive bacteria. The data showed that ciprofloxacin derivatives act as bidentate ligands and the metal ions coordinate through the pyridone carbonyl and the carboxylate oxygen atoms. Tetragonally distorted octahedral ligand fields were assumed for all complexes based on their spectral studies. Copper(II) complexes of the synthesized ciprofloxacin derivatives revealed higher antibacterial activities against gram-positive and gram-negative bacterial species than the parent ciprofloxacin antibiotic. Furthermore, three-dimensional quantitative structure-activity relationship (3D-QSAR) models were evaluated by studying 30 antibiotic compounds of the quinolone class. Density function theory (DFT) calculations were applied to evaluate the optimized geometrical structures using the B3LYP method and 6-311G(d,p) basis set. The 3D-QSAR study revealed that there are eight optimum parameters that give the best predictive modulation with good reliability (R-2= 0.996,F= 12.004, sigma = 0.426). In silico molecular docking was also performed on the derivatives, and the results revealed the presence of two types of interactions between theEscherichia coliand the derivatives, H-bonding and Van der Waals interactions, and an effective inhibition at the docked site.

New insight is provided into the chemistry of 12 para-substituted nitrobenzene compounds, using the high-level computational method G3(MP2) and DFT methods. The results show that the chemical properties of the nitrobenzene molecules, such as reduction potential, ionization energy, proton affinity, pK(a), interaction energy of the fragments, hyperpolarizability, exaltation index, band gap, UV electron excitation, and QTAIM properties, are controlled by the strong coupling between the nitro group (NO2) and the nature of the various para-substituents via the benzene ring as their conducting link. As the electron donating tendency of the para-substituent increases in the molecules, the electron cloud around the nitro group also increases, resulting in contraction of the N-C bonds and elongation of the N=O bonds, consequently leading to gradually increasing electron conductivity, polarizability, and ionization energy but lower proton affinity, thereby progressively impeding the reduction potential of the molecules. The experimental reduction potential was reproduced to a high degree of accuracy, with a mean absolute deviation (MAD) of 0.048V, depending on the computational method used and the choice of the free energy circle. Additionally, the experimental electron affinity and proton affinity of the 12 molecules were reproduced to a high degree of accuracy.

The difficulties in the separation of products from the reaction mixture and the recovery of the organic cationic ionic liquids (OCILs) catalysts still need to be addressed. Post modification of the pyridine unit in the covalent organic framework (COF) via the formation of pyridinium salts with the chiral bromoacetate led to the chiral ionic COF with OCIL immobilized, which was utilized as a heterogeneous catalyst for asymmetric Henry reactions with high yield and excellent stereoselectivity.

The electrochemical carbon-carbon bond formation process between beta-keto esters and silyl enol ethers was investigated utilizing manganese salts. The tricarbonyl compounds were generated in moderate to good yields under neutral conditions. Control experiments revealed that an electro-generated base at the cathode is important. Electro-analytical measurements with a Mn(TPA) complex suggested that the oxidation of the silyl enol ether is the first step in the oxidation process initiated by a corresponding Mn(IV) species.

The development of an asymmetric clip-cycle synthesis of 2,2- and 3,3-disubstituted pyrrolidines and spiropyrrolidines, which are increasingly important scaffolds in drug discovery programs, is reported. Cbz-protected bis-homoallylic amines were activated by clipping them to thioacrylate via an alkene metathesis reaction. Enantioselective intramolecular azaMichael cyclization onto the activated alkene, catalyzed by a chiral phosphoric acid, formed a pyrrolidine. The reaction accommodated a range of substitutions to form 2,2- and 3,3-disubstituted pyrrolidines and spiropyrrolidines with high enantioselectivities. The importance of the thioester activating group was demonstrated by comparison to ketone and oxoestercontaining substrates. DFT studies supported the aza-Michael cyclization as the rate- and stereochemistry-determining step and correctly predicted the formation of the major enantiomer. The catalytic asymmetric syntheses of N-methylpyrrolidine alkaloids (R)irnidine and (R)-bgugaine, which possess DNA binding and antibacterial properties, were achieved using the clip-cycle methodology.
