Facile rearrangement of push-pull 5-substituted 4-oxothiazolidines induced by pyridinium hydrobromide perbromide under homogeneous reaction conditions / Efikasno premeštanje push-pull 5-supstituisanih 4-oksotiazolidina indukovano piridinijum-hidrobromid-perbromidom pod homogenim reakcionim uslovima
(Serbian Chemical Society, 2004)
Pyridinium hydrobromide perbromide (PHBP) is a highly efficient reagent for the conversion of 5-substituted-2-alkylidene-4-oxothiazolidine derivatives to the corresponding thiazolidines with two fully delocalized exocyclic ...
Modeling of adsorber/desorber/catalytic reactor system for ethylene oxide removal / Modelovanje sistema adsorber/desorber/katalitički reaktor za uklanjanje etilen oksida
(Serbian Chemical Society, 2004)
The removal of ethylene oxide (EtO) in a combined system adsorber desorber/catalytic reactor has been investigated. The combined system was a modified draft tube spouted bed reactor loaded with Pt/Al2O3 catalyst. The annular ...
The synthesis and pharmacological evaluation of (+/-)-2,3-seco-fentanyl analogues / Sinteza i farmakološko ispitivanje (±)-2,3-seco-analoga fentanila
(Serbian Chemical Soc, Belgrade, 2004)
An efficient, five-step synthetic approach to various acyclic 1,3-diamines has been developed and applied to the preparation of a novel class of open-chained fentanyl analogues. The acyclic derivatives 5.1-5.5 (all new ...
Conformational analysis of guaianolide-type sesquiterpene lactones by low-temperature NMR spectroscopy and semiempirical calculations
(Kluwer Academic/Plenum Publ, New York, 2004)
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 ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni þ WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)
from a commercially available Watts bath containing additives for brightness and smoothing and insoluble ...
Covalent glycoinositolphospholipid (GPI) binding to hemoglobin is associated with insulin-activation of erythrocyte membrane protease / Kovalentno vezivanje glikoinozitolfosfolipida (GPI) za hemoglobin pod dejstvom insulina praćeno je aktiviranjem proteaze iz membrane eritrocita
(Serbian Chemical Soc, Belgrade, 2004)
Recently, it was demonstrated that prolonged hyperinsulinism associated with hypoglycemia, both in vivo and in vitro, caused covalent glycoinositolphospholipid (GPI) binding to the C termini of both hemoglobin beta-chains, ...
Interpretation of Serbian surface sediment maturation parameters based on factor analysis / Primena faktorske analize u interpretaciji maturacionih parametara površinskih sedimenata Srbije
(Serbian Chemical Society, 2004)
The factor analysis, used in this work for the interpretation of maturation parameters observed in an exploration study of a group of surface sediments of diverse age originating from different localities in Serbia, resulted ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
Flavonoids from flowers of Cephalaria pastricenis and their antiradical activity / Flavonoidi iz cvetova Cephalaria pastricensis i njihova antiradikalska aktivnost
(Serbian Chemical Society, 2004)
Two flavonoid glycosides 1 and 2 having the luteolin structure were isolated from flowers of the endemic plant species Cephalaria pastricensis. They were identified by 1H and 13C NMR, as well as UV/Vis spectroscopy. The ...
Photochemical and Beckmann rearrangement of (Z)-cholest-4-en-6-one oxime / Fotohemijsko i Bekmanovo premeštanje(z)-holest-4-en-6-on oksima
(Serbian Chemical Society, 2004)
Beckmann rearrangement of (Z)-cholest-4-en-6-one oxime (4) (prepared in 4 steps starting from cholest-5-en-3β-ol ο1)) with thionyl chloride in dioxane solution afforded an enamide-type lactam, i.e. 7-aza-B-homocholest-4-en-6-one ...
