The facile and clean oxidative biaryl coupling reaction of thiophenes and pyrroles has been achieved using the recyclable hypervalent iodine(III) reagents having adamantane or methane structures. These iodine(III) reagents could be recovered from the reaction mixtures by a simple solid-liquid separation, i.e., filtration.

We have developed a straightforward method to prepare 1(st) and 2(nd) generation adamantane-based dendrons, previously called HYDRAmers, bearing at the periphery the anti-inflammatory drug, ibuprofen. The multivalency effect on the drug activity was studied, demonstrating that our multivalent ibuprofen-dendron conjugates exert an enhanced anti-inflammatory activity compared to free ibuprofen, i...

3- And 9-component Pd(0) catalysed assembly of allenes, aryl iodides and N-nucleophiles with concomitant installation of trisubstituted Z-alkenes is readily achieved.

Self-assembled monolayers (SAMs) of tripod-shaped trithiols, consisting of an adamantane core with three CH2SH legs and a bithiophene group, were prepared on a Au(111) surface. Adsorption in a tripod-like fashion was supported by polarization modulation-infrared reflection absorption spectroscopy (PM-IRRAS) of the SAMs, which indicated the absence of free SH groups. Cyclic voltammetry showed an...

The reaction of Fe(CO)(2)(NO)(2) and Ni(N(2)S(2)) (N(2)S(2) = N,N'-Bis(2-mercaptoethyl)-1,4-diazacycloheptane) by a single CO replacement yields [Ni(N(2)S(2))]Fe(NO)(2)(CO), while an excess of Fe(CO)(2)(NO)(2) leads to triply bridging thiolate sulphurs in a cluster of core composition Ni(2)S(4)Fe(3), lacking one Fe(NO)(2) unit to complete the adamantane-like structure. This structural type was ...

The structure of the title compound, C(26)H(28)N(2)O(2), contains essentially planar quinoline and benzene rings, the maximum deviations from the best plane being 0.086 (2) and 0.0056 (19) Å, respectively; the dihedral angle between the rings is 82.87 (4)°. The adamantane cage consists of three fused cyclo-hexane rings in classical chair conformations, with C-C-C angles in the range 107.85 (15)...

It is shown that in nuclear magnetic resonance, multiple-quantum (MQ) coherences can be detected "instantly" by exploiting the principle of quantum-mechanical projective measurement. Therefore, the mixing period, which involves collective multispin dynamics and converts MQ coherences into observable single-quantum coherence (magnetization), is not necessary. The experimental examples are given ...

BACKGROUND Antiviral drugs are an important option for managing infections caused by influenza viruses. This study assessed the drug susceptibility of 2009 pandemic influenza A (H1N1) viruses collected globally between April 2009 and January 2010. METHODS Virus isolates were tested for adamantane susceptibility, using pyrosequencing to detect the S31N marker of adamantane resistance in the M2...
