Chemistry – A European Journal, EarlyView.At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Acta Pharmaceutica, 2014 Due to severe toxicity of pyrrolizidine alkaloids, their quantification in medicinal products is very important. The idea of this research was to use retrorsine as a surrogate reference compound instead of lycopsamine reference or lycopsamine isolated ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core
Chemistry – A European Journal, EarlyView.RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Chemistry – A European Journal, EarlyView.The development of chiral pda derived methoxy ligands L1a [1(R,R)] and L1b [1(S,S)], along with their phenol derivatives L2a [2(R,R)] and L2b [2(S,S)], and their respective Tb(III) complexes is described. These Tb‐complexes exhibited Tb(III)‐centered emission upon and their chiroptical properties were probed by using both CD and CPL spectroscopy ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Developmental Dynamics, EarlyView.Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1
EcoEnergy, EarlyView.A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...
