A series of HIV-1 integrase inhibitors containing a novel metal binding motif consisting of the 8-hydroxy-1,6-naphthyridine core and either an oxadiazole or triazole has been identified. The design of the key structural components was based on a two-metal coordination pharmacophore. This report presents initial structure-activity data that shows the new chelation architecture delivers potent inhibition in both enzymatic and antiviral assays.

Lanthanide triflates and a series of hexadentate chiral ligand complexes were synthesized. X-ray-quality crystals were obtained from mixtures of the lanthanide complexes, which were helical in shape. The complexes showed Lewis acidity and catalyzed the enantioselective Diels?Alder reaction of electron-rich siloxydienes. The complexes were stable enough to be stored at ambient temperature on a laboratory bench and retained their Lewis acidity even after a month.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 18531-99-2

Fluoroaromatic scaffolds pose a challenge to lithiation due to low stability of lithiated intermediates. Here we apply trans-metal-trapping (TMT) to a series of key fluorinated aromatics. In TMT, LiTMP performs the metalation, while an organometallic trap intercepts the emergent carbanion. This study contrasts the trapping abilities of iBu2AlTMP and Ga(CH2SiMe3)3, structurally mapping their TMT reactions and probing relative stabilities of metalated fluoroaromatic intermediates by NMR studies. Results show the installed Al?C(aryl) bonds are more prone to decomposition by benzyne formation and Li-F liberation, than the Ga?C(aryl) species. The latter are thus better for onward reactivity as demonstrated in cross-coupling reactions with benzoyl chloride that produce ketones.

The coordination complexes of trivalent f-element pertechnetates and perrhenates with some N-donor ligands were determined by using X-ray structural analysis: Nd3+ perrhenate with 2,6-bis(tetramethylfurano)-1,2,4-triazin-3-yl)-pyridine ([Nd(FBTP)3ReO4](ReO4)2 · 2H2O (I)), tris(2-pyridylmethyl)amine ([Nd(TPA)(ReO4)3] (II)) and N,N?-tetraethylmalonamide ([Nd(TEMA)4](ReO4)3 (III)). The coordination number of Nd is 10 in I, 9 in II and 8 in III. The complexes of Nd3+ pertechnetate and Am3+ pertechnetate with TPA have been also synthesized (Nd(TPA)(TcO4)3 (IV) and Am(TPA)(TcO4)3 (V)). The structure II does not change on replacement of perrhenate by pertechnetate and neodymium by americium.

Novel chiral iron phosphate complexes were prepared as catalysts for asymmetric oxidative coupling reactions. These catalysts were applied for the synthesis of enantio-enriched C1- and C2-symmetric BINOLs, in which the 3 and 3? positions are available for chemical modifications. It was proposed that the reaction takes place via an oxidative radical-anion coupling mechanism. A destructive BINOL racemization that competes with the enantioselective oxidative coupling of 2-naphthols was revealed, thereby offering new insights into this highly important reaction.

An enantioselective and non-oxidative methodology was developed to obtain enantioenriched cyclopropyl boronates using a diethanolamine-promoted selective decomplexation of dioxaborolane. The non-oxidative decomplexation of the dioxaborolane ligand from the cyclopropylmethoxide species formed in the dioxaborolane-mediated Simmons-Smith cyclopropanation reaction provided the enantioA-enriched CIDA-based (CIDA = N-cyclohexyliminodiacetic acid) boroA-cyclopropane in 92% yield and 95.6:4.4 er. A robustness screen has shown diethanolamine to be compatible with esters, carbamates and N-heterocycles, providing a tool to access enantioenriched cyclopropanes carrying not only base-sensitive but oxidizable functional groups as well. Diethanolamine was found to be compatible with the modified zinco-cyclopropanation reaction of allyl alcohol to remove residual dioxaborolane from the corresponding cis-N-heterocycle cyclopropylmethanol, thereby leading to improved yields.

Solid-state electrochemiluminescence (ECL) has drawn increasing attention due to its advantages over solution-phase ECL, such as reducing the consumption of expensive reagents and enhancing the ECL signal. Herein we report a ruthenium(ii)-polypyridyl doped zirconium(iv) metal-organic framework (MOF) film, UiO-67-Ru@FTO, for solid-state electrochemiluminescence. With tripropylamine (TPA) as a coreactant, UiO-67-Ru@FTO exhibited high ECL intensity and good stability. A linear relationship was found between the ECL intensity and TPA concentration in a wide range of 0.04-20 mM. Additionally, UiO-67-Ru@FTO was successfully used for dopamine detection, implying its great potential in real-life applications.

Reaction of vanadyl(IV)-acetylacetonate with 3-ethoxy-2-hydroxybenzaldehyde 4-methylthiosemicarbazone and 2,2?-bipyridyl in methanol affords a mononuclear oxovanadium(IV) complex containing VO(ONS) basic core. The complex has been characterized by various physicochemical techniques (UV?Vis, IR, and elemental analysis), and single-crystal X-ray diffraction. X-ray crystal structure determination reveals that the complex crystallizes as triclinic space group P 1, with unit cell dimensions a = 10.073(2) A, b = 11.272(3) A, c = 11.338(3) A, alpha = 87.291(2), beta = 83.440(2), gamma = 64.003(2), V = 1149.5(5) A3, Z = 2, R1 = 0.0356, wR2 = 0.0867, S = 1.052. The V atom in the complex is octahedrally coordinated, with the tridentate ONS ligand occupying the meridional sites. The nitrogen donor of 2,2?-bipyridyl ligand, occupying an apical position has a trans-labilizing influence, resulting in elongation of the V=O terminal bond. Thermal gravimetric analysis was performed to understand the stability of the complex. The complex shows high catalytic property and selectivity in the epoxidation of cyclohexene with t-butylhydroperoxide as oxidant.
