The synthesis, characterization, and electrochemical and photophysical properties of the phosphonate-derivatized carbazole (CBZ) and boron dipyrromethene (BODIPY) chromophores in the dyes, BODIPY(CBZ)(2)PO3H2 (8) and BODIPY(Tol)(2)PO3H2 (7), are described. The oxide-bound dyes have been explored as light absorbers in dyesensitized photoelectrosynthesis cell (DSPEC) applications. The BODIPY-CBZ phosphonate ester (6) features a broad, intense UV-visible absorption spectrum with absorptions at 297 and 650 nm that arise from mixed transitions at the CBZ and BODIPY units. Electrochemical measurements on BODIPY(CBZ)(2)Br (4) in 0.1 M [nBu(4)N] [PF6] in dichloromethane, vs normal hydrogen electrode (NHE), reveal reversible oxidations at 1.19 and 1.41 V and a reversible reduction at -0.59 V. On indium tin oxide (ITO) and TiO2, a reversible one-electron oxidation appears for 7 at 0.86 and 0.90 V vs NHE in dichloromethane, respectively, which demonstrates the redox stability on metal oxide surfaces. The results of nanosecond transient absorption measurements on SnO2/TiO2 electrodes provide direct evidence for excited-state electron injection into the conduction band of TiO2 following 590 nm excitation. A longer lifetime for 8(+) compared to 7(+) is consistent with extensive intramolecular charge separation between the CBZ and BODIPY units on the surface. Photoelectrochemical studies on 8 on a SnO2/TiO2 photoanode resulted in sustained photocurrents with current maxima of similar to 200 mu A/cm(2) with hydroquinone added as a reductant under 1 sun (AM1.5 100 mWcm(-2)) illumination at pH 4.5 in 0.1 M acetate buffer and 0.4 M LiClO4. On mixed SnO2/TiO2 electrode surfaces, with the added catalyst [Ru(Mebimpy)((4,4′-(OH)(2)PO-CH2)(2)bpy)(OH2)](2+) and chromophores 7 and 8, addition of 0.1 M benzyl alcohol resulted in sustained photocurrents of 12 and 35 mu A/cm(2), consistent with oxidation to benzaldehyde.

,-Unsaturated esters and lithium 1,3-dien-2-olates are known to furnish bicyclic lithium enolates by anionic Diels-Alder reactions. However, in principle, the respective products might form not only in a single step but also in two consecutive – or tandem – Michael additions, the first of which occurs intermolecularly, the second intramolecularly. Three cyclic lithium dienolates and four esters with a stereogenic C=C bond reacted to give Diels-Alder adducts (10 times) or failed to react (2 times). Seven of the reactive combinations furnished adducts wherein the configuration of the former ester moiety had in part inverted. This precludes concerted pathways as their origins. This was a surprise since donors at C-2 of the 1,3-diene accelerate normal electron-demand Diels-Alder reactions in the order alkyl < aryl < alkoxy approximate to trialkylsiloxy < acylamino. With (LiO?)-O-circle plus being a far better donor still, it is not obvious why the mechanism is non-concerted rather than concerted (and still more asynchronous). Formula: C5H8O2.

Herein we report the development of a photocatalytic strategy for the divergent preparation of functionalized bicyclo[1.1.1]pentylamines. This approach exploits, for the first time, the ability of nitrogen-radicals to undergo strain-release reaction with [1.1.1]propellane. This reactivity is facilitated by the electrophilic nature of these open-shell intermediates and the presence of strong polar effects in the transition-state for C-N bond formation/ring-opening. With the aid of a simple reductive quenching photoredox cycle, we have successfully harnessed this novel radical strain-release amination as part of a multicomponent cascade compatible with several external trapping agents. Overall, this radical strategy enables the rapid construction of novel amino-functionalized building blocks with potential application in medicinal chemistry programs as p-substituted aniline bioisosteres.

Direct oxidative coupling of different inert C-H bonds is the most straightforward and environmentally benign method to construct C-C bonds. In this paper, we developed a Pd-catalyzed intramolecular oxidative coupling between unactivated aliphatic and aryl C-H bonds. This chemistry showed great potential to build up fused cyclic scaffolds from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners.

Pyroligneous acid (PA) was obtained by condensation of the vapors produced in the thermal decomposition of culms residues from Guadua angustifolia Kunth (G. angustifolia) cultivated in Colombia, with and without previous preservation treatment with borax salts. Chemical characterization by GC-MS showed that PA extracts has high content of phenolic compounds. Mequinol, isocreosol, 4-ethylphenol, 4-ethyl-2-methoxyphenol, 3,5-dimethoxy-4-hydroxytoluene and 2,6-dimethoxyphenol were the most abundant substances, identified. The total phenolic content (TPC) and DPPH free radical scavenging activity, were investigated. TPC showed a concentration of 1.959 mg GA g(-1) +/- 0.010 and 3.844 mg GA g(-1) +/- 0.027 to PAC and PAS samples. These samples also exhibited high DPPH activity of 70.975%+/- 0.921 and, 16.667%+/- 0.298, respectively. The chemical composition, TPC and DPPH results indicate that the PA extracts obtained from G. angustifolia may be used as a raw material in the food industry as natural preservative, in medicine as alternative to antibiotics and in agriculture as insect repellent and foliar fertilizer.

Oligonucleotides incorporating a central C-nucleoside with either a rigid or flexible benzaldoxime base moiety have been synthesized, and the hybridization properties of their metallacyclic derivatives have been studied by UV melting experiments. In all cases, the metallated duplexes were less stable than their unmetallated counterparts, and the metallacyclic nucleobases did not show a clear preference for any of the canonical nucleobases as a base-pairing partner. With palladated oligonucleotides, increased flexibility translated to less severe destabilization, whereas the opposite was true for the mercurated oligonucleotides; this reflects the greater difficulties in accommodating a rigid Pd-II-mediated base pair than a rigid Hg-II-mediated base pair within the base stack of a double helix.

The addition of organometallic reagents to unsaturated bonds is one of the most powerful tools for carbon-carbon bond formations. Alkylation through organometallic reagents requires stoichiometric quantity of metal and tedious anhydrous operation in most cases. Here, we report umpolung nucleophilic additions of hydrazones to Michael acceptors, carbonyls and imines in water. Under the catalysis of ruthenium(II), the addition reactions could be carried out in pure water to provide various alkylation products in moderate to good yields. (C) 2020 Elsevier Ltd.

A novel technique called AOSD@Job’s, combining asynchronous orthogonal sample design scheme (AOSD) with Job’s method, is proposed to estimate the stoichiometric ratio of two substances that form a supramolecular aggregate under intermolecular interactions. First, a mathematical analysis was performed along with the procedure of the AOSD@Job’s method. Then, the validity of the AOSD@Job’s method was manifested by computer simulation on two model systems. Finally, the AOSD@Job’s method was applied on two real chemical systems. The stoichiometric ratio between the coordination complex of Ni2+ and ethylenediaminetetraacetic acid disodium salt (EDTA) was estimated to be 1.0. Benzyl alcohol (BA) and beta-cyclodextrin (beta-CD) were determined to form a 1 : 1 host-guest complex. These values were consistent with the values reported in the literature. Compared with the traditional Job’s method, the AOSD@Job’s method has an evident advantage since it is still valid even if all the peaks of the supramolecular aggregate severely overlap with the peaks of the substances that form the aggregate.

A visible-light photoredox-catalyzed tandem trifluoromethylation/cyclization/remote oxidation of 1,6-dienes has been achieved. A broad range of trifluoromethyl group-containing tetrahydrofurans or tetrahydropyrroles could be generated in good yields and with excellent diastereoselectivity by using dimethyl sulfoxide (DMSO) as the oxidant. The mild and facile protocol affords direct access to trifluoromethyl group-bearing tetrahydrofurans and tetrahydropyrroles via difunctionalization of olefins.

A tri-antennary Man(9)GlcNAc(2) glycan on the surface of endoplasmic reticulum (ER) glycoproteins functions as a glycoprotein secretion or degradation signal after regioselective cleavage of the terminal alpha-1,2-mannose residue of each branch. Four alpha-1,2-mannosidases-ER mannosidase I, ER degradation-enhancing alpha-mannosidase-like protein 1 (EDEM1), EDEM2, and EDEM3-are involved in the production of these signal glycans. Although selective production of signal glycans is important in determining the fate of glycoproteins, the branch-discrimination abilities of the alpha-1,2-mannosidases are not well understood. A structural feature of the Man(9)GlcNAc(2) glycan is that all terminal glycosidic linkages of the three branches are of the alpha-1,2 type, while the adjacent inner glycosidic linkages are different. In this study, we examined whether the alpha-1,2-mannosidases showed branch specificity by discriminating between different inner glycosides. Four trisaccharides with different glycosidic linkages [Man alpha 1-2Man alpha 1-2Man (natural A-branch), Man alpha 1-2Man alpha 1-3Man (natural B-branch), Man alpha 1-2Man alpha 1-6Man (natural C-branch), and Man alpha 1-2Man alpha 1-4Man (unnatural D-branch)] were synthesized and used to evaluate the hypothesis. When synthesizing these oligosaccharides, highly stereoselective glycosylation was achieved with a high yield in each case by adding a weak base or tuning the polarity of the mixed solvent. Enzymatic hydrolysis of the synthetic trisaccharides by a mouse liver ER fraction containing the target enzymes showed that the ER alpha-1,2-mannosidases had clear specificity for the trisaccharides in the order of A-branch > B-branch > C-branch approximate to D-branch. Various competitive experiments have revealed for the first time that alpha-1,2-mannosidase with inner glycoside specificity is present in the ER. Our findings suggest that exo-acting ER alpha-1,2-mannosidases can discriminate between endo-glycosidic linkages.
