A new lanthanide-sensitized luminescence system: europium-sparfloxacin-1,10-phenanthroline-sodium dodecyl sulfate has been discovered. The spectrofluorimetric properties of the system were studied. The effect of experimental conditions on the fluorescence intensity was defined. Under the optimum conditions, the fluorescence intensity of the system is a… (More)
A novel series of p-terphenyl derivatives (1-4, 1a-4a) was successfully synthesized and their in vitro anticancer activities were evaluated. Compound 1, showing the best antiproliferative activity with IC50<1 μM against MDA-MB-435 cells, was further investigated. Compound 1 brought about a remarkable accumulation of MDA-MB-435 cells in G2/M phase prior to… (More)
A Cu/Pd-catalyzed, three-component click reaction of azide, alkyne, and aryl halide has been developed. By using this Cu/Pd transmetalation relay catalysis, a variety of 1,4,5-trisubstituted 1,2,3-triazoles were quickly assembled in one step in high yields with complete regioselectivity, just like assembling Lego bricks. Notably, different from the… (More)
In the title complex, [Cd(C(2)F(3)O(2))(NO(3))(C(10)H(8)N(2))(2)], the Cd(II) ion is hepta-coordinated by two chelating 2,2'-bipyridyl ligands [Cd⋯N 2.370 (6)-2.416 (6) Å], one carboxyl-ate O atom [Cd⋯O 2.290 (6) Å] from the trifluoro-acetate ligand and two O atoms [Cd⋯O 2.386 (6), 2.633 (6) Å] from a chelating nitrate anion. The trifluoro-methyl fragment… (More)
The first example of transition metal-free enantioselective 1,2-silylation of aromatic aldehydes is reported. This protocol enables an easy access to chiral α-hydroxysilanes from readily available aromatic aldehydes.
Quantum dots (QDs) that are conjugated to small molecule derivatives of drugs and endogenous ligands may be useful tools to study the distribution and dynamic of membrane bound receptors, ion channels and transporters in live cells. In order to use these tools, it is necessary to functionalize QDs with bioactive ligands. In this paper, we successfully… (More)
An efficient copper-catalyzed asymmetric conjugate boration has been achieved by exploiting a new planar and central chiral bicyclic triazolium ligand. This protocol was highly efficient and gave a variety of chiral secondary alkylboronates in 97-99% ee. A preliminary mechanistic study supports the bifunctional nature of the catalyst.
[structure: see text] Bulky phenanthracenyl imidazolium-derived carbene ligands were investigated for copper-free Sonogashira coupling with terminal acetylenes. Aryl bromides and iodides gave coupled products in excellent yields from the Pd(PPh(3))(2)Cl(2) complex with potassium t-butoxide and 18-crown-6 in THF. A remarkable dependence on the size of the… (More)
The title compound, C(23)H(19)BrO(2), was synthesized from 13-bromo-4-hy-droxy[2.2]paracyclo-phane and benzoyl chloride. The hy-droxy and carbonyl groups are involved in intra-molecular O-H⋯O hydrogen bonding. The crystal packing exhibits weak C-H⋯O inter-actions, which link the mol-ecules into sheets parallel to the bc plane.
