AB  - The rotational barriers between the configurational isomers of two structurally related push-pull 4-oxothiazolidines, differing in the number of exocyclic C=C bonds, have been determined by dynamic H-1 NMR spectroscopy. The equilibrium mixture of (5-ethoxy-carbonylmethyl-4-oxothiazolidin-2-ylidene)-1-phenylethanone (1a) in CDCl3 at room temperature to 333 K consists of the E- and Z-isomers which are separated by an energy barrier Delta G(#) 98.5 kJ/mol (at 298 K). The variable-temperature H-1 NMR data for the isomerization of ethyl (5-ethoxycarbonylmethylidene-4-oxothiazolidin-2-ylidene)ethanoate (2b) in DMSO-d(6), possessing the two exocyclic C=C bonds at the C(2)- and C(5)-positions, indicate that the rotational barrier Delta G(#) separating the (2E,5Z)-2b and (2Z,5Z)-2b isomers is 100.2 kJ/mol (at 298 K). In a polar solvent-dependent equilibrium the major (2Z,5Z)-form ( gt  90%) is stabilized by the intermolecular resonance-assisted hydrogen bonding and strong 1,5-type (SO)-O-... interactions within the S-C=C-C=O entity. The C-13 NMR Delta delta(C(2)C(2')) values, ranging from 58 to 69 ppm in 1a-d and 49-58 ppm in 2a-d, correlate with the degree of the push-pull character of the exocyclic C(2)=C(2') bond, which increases with the electron withdrawing ability of the substituents at the vinylic C(2') position in the following order: COPh similar to COEt  gt  CONHPh  gt  CONHCH2CH2Ph. The decrease of the Delta delta(C(2)C(2')) values in 2a-d has been discussed for the first time in terms of an estimation of the electron donor capacity of the -S- fragment on the polarization of the C=C bonds.

AB  - Conformational analysis of 9alpha-acetoxycumambrine A 1 and 8-O-isobutiryl-9alpha-acetoxycumambrine B 2 was carried out by low-temperature NMR studies. Results suggested that lactones 1 and 2 are mixtures of two distinctive conformers, I and II. Based on low-temperature H-1 NMR spectra, in four solvents, the thermodynamic parameters of I reversible arrow II exchange process were assessed. Energy of activation of I -- gt  II reaction was obtained by dynamic NMR simulations for both compounds. Results revealed that conformational exchange of lactones 1 and 2 occurs due to "chair reversible arrow twisted chair" interconversion of a heptane ring. The same PM3 semiempirical method was applied for geometry optimization of lactones 1 and 2, as well as of 9alpha-hydroxycumambrine A 3, 9alpha-acetoxycumambrine B 4, and cumambrine B 5.

AB  - Rotamer population of S-tyrosinato and S-phenylalaninato ligands side groups in diastereomers of (1,2-diaminoethane)bis(S-aminocarboxylato)cobalt(III) complexes is calculated by vicinal alpha and beta proton coupling constant analysis. The effect of noncovalent intra- and interligand interactions on the population of rotamers in D2O solution is discussed. It has been established that in all the complexes investigated the most abundant is rotamer t, in which aromatic voluminous moiety and carboxylic group are in an anti position. In almost all complexes the lowest content is of rotamer g, in which these two groups are in the nearest position. Relatively high population of rotamer b in complex 5 tyr, in spite of high steric hindrances, is due to intra- and interligand NH... pi interactions.

AB  - In the reaction of trans-[CoCl2(en)(2)](+) with L-tyrosine all six theoretically possible diastereomers of the (1,2-diaminoethane)bis(L-tyrosinato)cobalt(III) complex were formed. The following five were isolated: Delta -trans(O); and Lambda- and Delta -C-2-cis(O) and Lambda- and Delta -C-1-cis(O) diastereomers, while the Delta -trans(O) diastereomer was only detected in the corresponding eluate. Separation of the obtained diastereomers was performed by chromatography on a Dowex 1 x 4 column. Characterization of the isolated diastereomers was carried out by means of elemental analysis, electronic absorption, circular dichroic, H-1 and C-13 NMR spectra, and by x-ray crystal structure analysis in the case of the Delta -C-1-cis(O) diastereomer. We established the general rule of preference of diasteromers formation in complexes of [Co(L-aa)(2)diamine](+) (L-aa = L-amino acid anion; diamine = 1,2-diaminoethane or 1,3-diaminopropane) type.

AB  - The thermal decomposition of Fe(III) and Ni(II) complex compounds with beta-diketonato ligands i.e., acetylacetone (AA), benzoylacetone (BA) and dibenzoylmethane (DBM), were investigated. The goal was to produce ultrafine metalic oxide powders (NiOxFe(2)O(3)) as precursors for the preparation of nickel-ferrite (NiFe2O4). The thermal decomposition of these materials wets carried out by simultaneous TG/DTG/DTA analysis. The materials produced by this method were characterized by X-ray powder diffraction and transmission electron microscopy (TEM). Within the interpretation of results, the formation of nickel-ferrite (NiFe2O4) in comparison to the production of single oxides (NiO and Fe2O3) was especially interesting. At low temperatures (below 600 degrees C), the ultrafine ferrite materials were obtained from complex compounds as precursors. The ferritization rate increases in the series from DBM, BA to AA. The materials formed by the thermal decomposition of the complex compoounds mixtures, with AA as the ligand, with average particle size of Ig nm shaw favorable physico-chemical properties.

In addition, one of them, with the same number of carbons as hyperforin (C35H52O5), contained a 1-methyl-1-hydroxyethyl group in the 6 beta-position, whereas the other compound (a hemiacetal, C32H46O5), presumably a degradation product of hyperforin, exhibited a 6-hydroxy function.

AB  - The genus Anthemis L. (family Asteraceae, tribe Anthemidae) comprises about 130 species that commonly occur in the Mediterranean, although some also can be found in southwest Asia and South Africa.(1) In Serbia nine species are known.(2) Three main classes of compounds of chemosystematic interest, such as polyacetylenes, flavonoids, and sesquiterpene lactones, typical for Anthemidae, have been detected in the genus Anthemis.(3,4) Among the sesquiterpene lactones, only three types, that is, germacranolides (and seco-germacranolides),(5-15) eudesmanolides,(16,17) and guaianolides,(5,14,18,19) 19 have been isolated from the genus. The exception is an allergenic lactone with unusual structure (anthecotuloide), the constituent of A. cotula.(20,21) Continuing our chemotaxonomic examinations of the Yugoslavian flora belonging to Asteraceae and our search for new compounds of pharmacological interest, we now report the investigation of the aerial parts of Anthemis carpatica Willd, a species usually occurring at elevated, shady and grassy, sandy terrains of the Balkan Peninsula, eastern Alps, and east Carpathian Mountains.(2) A flavonoid quercetin(22) (leaves) and polyacetylenes(4) (roots) are the only secondary metabolites reported for A. carpatica.

The exception is an allergenic lactone with unusual structure (anthecotuloide), the constituent of A. cotula.(20,21) Continuing our chemotaxonomic examinations of the Yugoslavian flora belonging to Asteraceae and our search for new compounds of pharmacological interest, we now report the investigation of the aerial parts of Anthemis carpatica Willd, a species usually occurring at elevated, shady and grassy, sandy terrains of the Balkan Peninsula, eastern Alps, and east Carpathian Mountains.(2) A flavonoid quercetin(22) (leaves) and polyacetylenes(4) (roots) are the only secondary metabolites reported for A. carpatica.",

AB  - 4-Morpholine-, piperidine-, 4-piperazine- and N-methyl- piperazine-dithiocarbamate complexes of Cobalt (III) with 1, 4, 8, 11-tetraazacyclotetradecane, of general formula [Co(Rdtc)cyclam] (ClO4)(2), have been prepared and have been characterized. The complexes adopt cis-octahedral geometry with folded macrocyclic ligand and with the dithiocarbamate bound as a bidentate. trans-influence of the dithiocarbamate ligands was studied by NMR spectroscopy and established the order piperidine-dtc  gt 4-morpholine-dtc gt N-methyl-piperazine-dtc.
