Eb. Zeinalov et al., Synthesis and reactivity of antioxidants based on vernolic acid and 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid, ANGEW MAKRO, 260, 1998, pp. 77-81
The reactivity of sterically hindered phenols toward free radicals of the h
ydrocarbon cumene was studied. New compounds, i.e. methyl cis-13(12)-(3-(3,
5-di-tert-butyl-4-hydroxyphenyl)propionyloxy)-12(13)-hydroxyoleate and cis-
13(12)-(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxy)-12(13)-hydroxyol
eic acid were synthesized starting from vernolic acid and its methyl ester,
respectively, and 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid. Bot
h new compounds possess antioxidant activities similar to those of commerci
ally available antioxidants.
