Reaction of benzoxanthene lignans with peroxyl radicals in polar and non-polar media: cooperative behaviour of OH groups

Autor: Corrado Tringali, Carmela Spatafora, Riccardo Amorati, Carmelo Daquino

Benzo[kl]xanthene lignans, promising bioactive polyphenols obtained by biomimetic oxidative coupling of caffeic acid derivatives, react efficiently with peroxyl radicals in both polar and non-polar solvents, thanks to the simultaneous presence of gua
