Abstract Two phenol based esters phenyl benzoate (OE1) and 1-naphthyl benzoate (OE2) were synthesized from phenol/1-naphthol and benzoyl chloride respectively. The structural elucidation of the synthesized compounds was accomplished by spectroscopic studies (FTIR, 1H NMR & GC-MS) and single crystal X-ray diffraction analysis. DPPH (2, 2-diphenyl-1-picryl-hydrazyl-hydrate) free radical and hydrogen peroxide activities were performed to evaluate the antioxidant capabilities of the synthesized este...

Abstract This article focus on the synthesis of three 5-coordinated Sn(IV) complexes based on carboxylate ligand: 4-((4-methoxy-2-nitrophenyl)amino)-4-oxobutanoic acid. The complexes were characterized in both solid state (FT-IR, single crystal XRD and micro elemental analysis) as well as in solution state (1H, 13C and 119Sn NMR) and their results demonstrate that the carboxylate moiety of the ligand is linked with Sn atom. A 5-coordinated trigonal bipyramidal structure was obtained from crystal...

13C solid-state MAS NMR spectra of a series of paramagnetic metal acetylacetonate complexes; [VO(acac)2] (d1, S = ½), [V(acac)3] (d2, S = 1), [Ni(acac)2(H2O)2] (d8, S = 1), and [Cu(acac)2] (d9, S = ½), were assigned using modern NMR shielding calculations. This provided a reliable assignment of the chemical shifts and a qualitative insight into the hyperfine couplings. Our results show a reversal of the isotropic 13C shifts, δiso(13C), for CH3 and CO between the d1 and d2 versus the d8 and d9 ac...

Abstract The steady rise of the antimicrobial resistance is a major global threat to human health that requires the urgent need for novel antibiotics. In this work we report the synthesis of a small library of 3-subsituted-5-arylidene tetramic acids in order to investigate the scope of our previously established methodology via an intermediate oxazolone and their antimicrobial activity. From this series of 14 tetramic acids, 11 derivatives are novel and one of them is a Schiff base, which was st...

Abstract Two new phthalonitriles 1 and 2, extended with biphenylethynyl and diphenylacetylenyl, were synthesized through a combination of Corey-Fuchs and palladium-catalyzed Sonogashira coupling reactions. The structures of 1 and 2 were revealed through single-crystal X-ray analysis. Cyclotetramerization of these phthalonitriles led to the corresponding 1,4,8,11,15,18,22,25-octabutoxy-2,3,9,10,16,17,23,24-octakis(biphenyl) and (diphenylacetylenyl) phthalocyanines. The longer substituent, namely ...

Herein, we report the synthesis, characterisation, X-ray crystallography, and oxidative DNA binding interactions of the copper artificial metallo-nuclease [Cu(DPQ)2(NO3)](NO3), where DPQ = dipyrido[3,2-f:2′,3′-h]quinoxaline. The cation [Cu(DPQ)2]2+ (Cu-DPQ), is a high-affinity binder of duplex DNA and presents an intercalative profile in topoisomerase unwinding and viscosity experiments. Artificial metallo-nuclease activity occurs in the absence of exogenous reductant but is greatly enhanced by ...

When InBr3-EtAlCl2 (15–30 mol%) was used as a dual Lewis acid system to promote the formal [3+2]-cycloaddition of enantioenriched donor–acceptor cyclopropanes with ketenes, cyclopentanones were formed in good to excellent yields (84–99%, 18 examples), and with excellent transfer of chirality (15 examples, 90% ee to >99% ee).

The single crystal X-ray structure determination of {[Cu(tpt)(o-phthalate)]·31/3(C2H2Cl4)}n (tpt = 2,4,6-tri-4-pyridyl-1,3,5-triazine, C2H2Cl4 = 1,1,2,2-tetrachloroethane = TCE) shows a 3D network in which CuII centres are linked by 3-connecting tpt ligands with the topology of a 12,3 net. CuII centres are further linked by o-phthalate dianions. The copper coordination geometry is square pyramidal, with o-phthalate oxygen donors trans to each other in the basal plane and the remaining positions ...

In this article we describe a new asymmetric synthesis of highly substituted tetrahydrofurans through a Pd(PPh3)4-catalyzed formal [3 + 2]-cycloaddition of donor–acceptor cyclopropanes and ketenes. The desired structural motif was formed in moderate to excellent yields (42–84% for 16 examples), with excellent Z:E isomer diastereoselectivity (≥19:1 for 16 examples), and with good to excellent enantioselectivity in all cases examined (83–97% ee for 6 examples). The synthetic utility of the product...
