Abstract
The antioxidant activity of 2-aminothiazoles containing a diterpene fragment in a model system of initiated radical-chain oxidation of 1,4-dioxane was evaluated. The compounds exhibited different inhibitory activities depending on their structure. The effective rate constant of the interaction of substituted 2-aminothiazoles with the 1,4-dioxane peroxyl radical was measured. 2-Aminothiazoles obtained by the chemical transformations of maleopimaric acid N-phenylamide showed higher reactivity with the peroxyl radical.
