Oxidation of a vitamin E model compound, 2,2,5,7,8-pentamethylchroman-6-ol, with the t-butylperoxyl radical
Abstract
In a t-butylperoxyl radical-generating system, a vitamin E model compound, 2,2,5,7,8-pentamethylchroman-6-ol, was converted into 4a,5-epoxy-4a,5-dihydro-8a-hydroperoxy-2,2,5,7,8-pentamethylchroman-6(8aH)-one (3), the structure of which has been determined by X-ray crystallography, and 8a-t-butyldioxy-4a,5-epoxy-4a,5-dihydro-2,2,5,7,8-pentamethylchroman-6(8aH)-one (4).
