Conformational stability of 5-substituted orotic acid derivatives analyzed by measuring C-13 NMR chemical shifts and applying linear free energy relationships
(Elsevier, Amsterdam, 2019)
Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the C-13 NMR chemical shifts. The correlation analysis for the substituent-induced ...
Synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalysed by amino acids / Sinteza 4,6-dimetil-3-cijano-2-piridona katalizovana aminokiselinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In this work the synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalyzed by amino acids was studied. In the first part of the work, the optimization was carried out by varying the initial concentration of glycine, the molar ...
