Cyclization/alkoxy radical fragmentation tandem: An efficient approach to the synthesis of bridged cyclooctane derivatives
(Journal of the Serbian Chemical Society, 1997)
In this paper an efficient synthetic approach to bridged cyclooctanone framework is described, which is based on cyclization/alkoxy radical fragmentation as a tactical combination of reactions. While the hypoiodite reaction ...
Isolation and partial characterization of a lectin from the marine sponge Crambe crambe
(Journal of the Serbian Chemical Society, 1996)
A lectin was isolated from the marine sponge Crambe crambe. The lectin is a monomeric glycoprotein with relative molecular mass of 14000. It agglutinates sheep and human red blood cells. The agglutination was found to be ...
The preparation of N-alkyl acyclic imides
(Journal of the Serbian Chemical Society, 1996)
An optimized method for the preparation of a little known class of compounds, acyclic imides, is described. First, the N-metalation of selected secondary am des was examined, using various bases and solvents. The most ...
Preparation and characterization of meridional isomers of uns-cis-(ethylenediamine-N,N'-di-3-propionato)cobalt(III) complexes with some β-amino acids
(Journal of the Serbian Chemical Society, 1996)
The meridional geometrical isomers of uns-cis-(ethylenediamine-N,N ′-di-3-propionato)cobalt(III) complexes with anions of β-alanine, β-amino-buteric and β-amino-isobuteric acids were prepared in the reaction of sodium ...
The preparation of an isoxazole derivative of 4-hydroxycoumarin
(Serbian Chemical Soc, Belgrade, 1998)
A method for preparation of an isoxazole derivative of 4-hydroxycoumarin, 3-phenyl-5-(4-hydroxy-3-coumarinyl)-isoxazole has been described. The reaction sequence includes addition of bromine to 3-cinnamoyl-4-hydroxycoumarin, ...
Synthesis and characterization of s-cis-bis(ethylenediamine-N,N′-diacetato)-μ-O,O′-glycinato-μ- hydroxo-dichromium(III)monohydrate
(Journal of the Serbian Chemical Society, 1997)
The reaction between s-cis-diaqua-(ethylenediamine-N,N′-diacetato)-chromium(III) nitrate and glycine (mole ratio 1:1, pH = 6, 80 °C, 2 h) results in the formation of two nonelectrolytic compounds. One of them was identified ...
