(Association of the Chemical Engineers of Serbia, 2004)
U radu je opisana sinteza blok kopolimera sa poli(butilentereftalatnim) tvrdim segmentima i poli(dimetilsiloksanskim) mekim segmentima. Cilj rada je da se ispita iproveri da lije primenljiva klasična metoda dvostepene ...
7, 8, 15, 16-Tetraoxa-dispiro [5. 2. 5. 2]hexadecane-3-carboxylic acid derivatives and their antimalarial activity / Antimalarijska aktivnost derivata 7,8,15,16-tetraoksa-dispiro5.2.5.2heksadekan-3-karboksilne kiseline
(Serbian Chemical Society, 2004)
Several C2 symmetrical mixed tetraoxanes were prepared starting from a gemdihydroperoxide and a ketone. The obtained tetraoxanes showed pronounced antimalarial activity against P. falciparum chloroquine resistant W2 and ...
Stereoselective synthesis of α-hydroxy-β-amino acids: The chiral pool approach / Stereoselektivne sinteze α-hidroksi-β-aminokiselina iz prirodnih hiralnih prekursora
(Serbian Chemical Society, 2004)
A method for the stereoselective homologation of -amino acids into syn-α-hydroxy-β-amino acids is described, based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the ...
Effect of MnSOD (E. coli) on the relaxation caused by sodium nitroprusside on isolated rat renal artery / Efekat MnSOD (E. coli) Na relaksaciju izolovane renalne arterije pacova izazvanu natrijum-nitro-prusidom
(Serbian Chemical Society, 2004)
In this study themolecular foundation of nitric oxide induced relaxation of arteries, with or without endothelium, of normotensive and spontanously hypertensive ratswas re-examined. With this purpose in mind, the effects ...
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
Synthesis of 5-azaandrostane-3β,17β-diol protected at the 17β-hydroxyl group
(Serbian Chemical Society, 2004)
In the present paper, the preparation of 3β-hydroxy-17β-dimethyl- tert-butylsilyloxy-5-azaandrostane (15) in fourteen steps is described. B-nor-17-oxoandrost-5-en-3β-yl acetate (1) 1,2 was used as the starting material, ...
Thionation of N-methyl- and N-unsubstituted thiazolidine enaminones / Tionovanje n-metil- i n-nesupstituisanih tiazolidinonskih enaminona
(Serbian Chemical Society, 2004)
The potential of directional non-bonded 1,5-type S···O interactions to initiate the incipient stage of an in situ rearrangement of N-unsubstituted thiazolidine enaminones to functionalized 1,2-dithioles has been demonstrated. ...
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 ...
New method of Ni/WC and Cu/WC composite coatings formation / Novi način formiranja kompozitnih prevlaka
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
Ni/WC and Cu/WC composite coatings were obtained in two steps. The first step consists of the inert WC particles deposition from the aqueous solution onto steel surface by means of a micro-pipette and covering by the dilute ...
