Direct Photoredox-Catalyzed Reductive Difluoromethylation of Electron-Deficient Alkenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Tang XJ, Zhang Z, Dolbier WR.
PMID: 26527168
Chemistry. 2015 Dec 21;21(52):18961-5. doi: 10.1002/chem.201504363. Epub 2015 Nov 17.

Photoredox-catalyzed reductive difluoromethylation of electron-deficient alkenes was achieved in one step under tin-free, mild and neutral conditions. This protocol affords a facile method to introduce RCF2 (R=H, Ph, Me, and CH2N3) groups at sites β to electron-withdrawing groups. It...

Xu ZH, Wang DY, Yang LJ, Wei ZM.
PMID: 24253473
Plant Cell Rep. 1984 Aug;3(4):149-50. doi: 10.1007/BF00270210.

Young inflorescence explants of Setaria italica in culture showed high capacity for regenerating plantlets through somatic embryogenesis. Embryogenic callus formation was initiated from the explants cultured on Murashige and Skoog's medium with 2 mg/l 2,4-D and 0.2-0.5 mg/l KT...

Pd-catalyzed allylic alkylation of dienyl carbonates with nitromethane with high C-5 regioselectivity.

PMID: 24266021
Chem Commun (Camb). 2014 Jan 14;50(4):484-6. doi: 10.1039/c3cc46574h.

A highly regioselective palladium-catalyzed allylic alkylation of dienyl esters with nitromethane has been developed, providing selective access to the C-5 attacked products. The structures of the ligands as well as the steric effect of the substrates are important factors...

Photocatalytic Radical Trifluoromethylation/Cyclization Cascade: Synthesis of CF3-Containing Pyrazolines and Isoxazolines.

Organic letters

Wei Q, Chen JR, Hu XQ, Yang XC, Lu B, Xiao WJ.
PMID: 26332823
Org Lett. 2015 Sep 18;17(18):4464-7. doi: 10.1021/acs.orglett.5b02118. Epub 2015 Sep 02.

A general visible light induced photoredox-catalyzed radical trifluoromethylation/cyclization cascade of β-aryl-β,γ-unsaturated hydrazones and oximes is described. The protocol enables an efficient access to various densely functionalized and biologically important CF3-containing dihydropyrazoles and isoxazolines with generally high yields.

Autophagy in Ischemic Livers: A Critical Role of Sirtuin 1/Mitofusin 2 Axis in Autophagy Induction.

Toxicological research

Chun SK, Go K, Yang MJ, Zendejas I, Behrns KE, Kim JS.
PMID: 26977257
Toxicol Res. 2016 Jan;32(1):35-46. doi: 10.5487/TR.2016.32.1.035. Epub 2016 Jan 31.

No-flow ischemia occurs during cardiac arrest, hemorrhagic shock, liver resection and transplantation. Recovery of blood flow and normal physiological pH, however, irreversibly injures the liver and other tissues. Although the liver has the powerful machinery for mitochondrial quality control,...

Rare double spin canting antiferromagnetic behaviours in a [Co24] cluster.

Chemical communications (Cambridge, England)

Liang GM, Ni QL, Zou HH, Gui LC, Wang XJ.

Chem Commun (Camb). 2016 Apr 18;52(30):5293-6. doi: 10.1039/c6cc00568c. Epub 2016 Mar 22.

A fish-basket-shaped [Co24] cluster, [Co24(μ3-O)4(ampc)4(μ3-OH)4(μ2-OH)4(NO3)5(HCO2)22(H2O)10]·[(HCO2)·2(CH3OH)·x(H2O)], was woven by bridging oxygen atoms from O(2-), OH(-), NO3(-) and HCO2(-) groups, and stabilized terminally by a semi-rigid organic ligand 4',4'-[(dimethylamino)dimethylene]-bis[(1,1'-biphenyl)-2-carboxylate] (ampc(-)). Magnetic analyses indicate that the [Co24] cluster exhibits two types of...

Molecular systematics of the Labeonini inhabiting the karst regions in southwest China (Teleostei, Cypriniformes).

The major phylogenetic pattern of the cyprinid tribe Labeonini has been revealed by previous molecular studies; however, the relationships within a clade that mainly inhabits the karst regions, which we refer to as the "karst group", in southwest China...
