A new Cu-catalyzed efficient protocol is described for the transformation of oximes to the corresponding carbonate derivatives. Diisopropyl azodicarboxylate acted as a selective new precursor for the synthesis of oxime carbonates in high yields. The O-H bond cleavage and O-C bond formation occur in the presence of a copper catalyst providing a synthetically useful process, which tolerates a wid...

In the title compound, (C(10)H(24)N)(2)[Cu(2)Cl(6)], N,N-diisopropyl-butanamine is protonated on the N atom. The Cu(II) atom in the centrosymmetric [Cu(2)Cl(6)](2-) anion has a distorted tetra-hedral geometry. In the crystal, the cations and anions are connected by N-H⋯Cl and C-H⋯Cl hydrogen bonds into layers parallel to (100).

Penetration measurements through commercially available filtering facepieces were performed with monodisperse DEHS aerosols ranging from 0.03 μm to 0.40 μm (either singly charged or neutralized), before and after 500 mg of paraffin oil loading. The distinct behavior of Coulomb and polarization capture efficiency is studied: as in the case of non loading also in the case of loading 500 mg of par...

The title compounds, variously protected 5'-uridine derivatives connected with 1-thiosugar with thio-phosphoesters fragment (17-22) were synthesized in sequence of reactions: phosphitylation--reaction of 5'-hydroxyl group of selectively protected nucleoside with a phosphitylating agent (N,N-diisopropyl chlorophosphoamidite), connection an phosphoroamidites with 2-bromoethanol or 3-bromopropanol...

The pharmacokinetics of disodium sebacate (Sb) was studied in Wistar rats of both sexes. Sebacate was administered either as intra-peritoneal (i.p.) bolus (six doses ranging from 10 mg to 320 mg) or as oral bolus (two doses: 80 and 160 mg). Plasma and urinary concentrations of Sb and urinary concentrations of Sb and its products of beta-oxidation (suberic and adipic acids) were measured by an i...
