Carbon-bromine cleavage by dimethyl sulfoxide: the key step of C(5) functionalization of push-pull 2-alkylidene-4-oxothiazolidine vinyl bromides
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Push-pull 2-alkylidene-4-oxothiazolidine vinyl bromides undergo efficient C(5) functionalization through DMSO-assisted carbon-bromine cleavage, followed by a bromine transfer-substitution (or elimination) sequence. A ...
Volatile constituents of Achillea serbica Nym.
(John Wiley & Sons Ltd, W Sussex, 2000)
The volatile constituents of Achillea selbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...
Generation and intermolecular additions of pyridylmethyl radicals
(Georg Thieme Verlag Kg, Stuttgart, 2008)
2-, 3-, or 4-Pyridylmethyl radicals can be made to add to nonactivated alkenes to give a variety of otherwise inaccessible pyridine derivatives. Bicyclic structures can be obtained by combining the radical addition with ...
Synthesis, characterization and antitumor activity of novel N-substituted alpha-amino acids containing ferrocenyl pyrazole-moiety
(Elsevier Science Sa, Lausanne, 2009)
A series of new N-[(3-ferrocenyl-1-phenylpyrazol-4-yl)methyl] alpha-amino acids were prepared and characterized by a range of spectroscopic techniques and cyclic voltammetry. The in vitro antitumor activity of all synthesized ...
DFT and MM description of the structure and magnetic properties of manganese complexes with X-phenylcyanamido bridging ligand

Magnetic properties of the complexes [Mn(3-Clpcyd)(H(2)O)-(phen)(2)](+), [{Mn(3-Fpcyd)(MeOH)(phen)}(2)(mu-3-Fpcyd)(2)], [{Mn(3-Fpcyd)(EtOH)(phen)}(2)(mu-3-Fpcyd)(2)], [{Mn(3-Clpcyd)(MeOH)(phen)}(2)(mu-3-Clpcyd)(2)], and ...
Computational analysis of tris(1,2-ethanediamine) cobalt(III) complex ion: calculation of the Co-59 shielding tensor using LF-DFT
(Springer Wien, Wien, 2011)
The ligand-field density functional theory (LF-DFT) approach is employed for calculations of the Co-59 nuclear magnetic resonance (NMR) shielding tensor of all four diastereoisomers (lambda lambda lambda, lambda lambda I ...
Density functional theory study of the magnetic coupling interaction in a series of binuclear oxalate complexes
(Springer Wien, Wien, 2012)
Magnetic couplings in oxalate-bridged binuclear complexes, namely five isomers of [(VO)(2)(ox)(SCN)(6)](4-), trans-(equatorial, equatorial), cis-(equatorial, equatorial), trans-(axial, axial), cis-(axial, axial), and (axial, ...
A convenient procedure for the preparation of Garner's aldehyde
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The palladium/silane reduction of a serine thioester derivative allows for the preparation of enantiomerically pure Garner's aldehyde from serine, in gram quantities within 24 h.
Kinetics and mechanism of the reactions of Ru(II)-arene complex with some biologically relevant ligands
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The reactions of ruthenium(II)-arene complex [Ru-II(eta(6)-p-cym)(pydc)Cl] (where p-cym = p-isopropyl toluene, pydc = 2,3-pyridinedicarboxylato) with biologically nitrogen-donor nucleophiles, such as guanosine-5'-monophosphate ...
Cholesterol bound to hemoglobin in normal human erythrocytes: a new form of cholesterol in circulation?
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Objective: To study lipid fraction that is occasionally observed in red blood cell (RBC) hemolysate (supernatants from which membranes were separated). Study design: Plasma lipid profiles, cholesterol (Ch) and phospholipids ...
