From catechol‐tocopherol to catechol‐hydroquinone polyphenolic antioxidant hybrids

open access: yesHeteroatom Chemistry, 2018
AbstractMultidefence antioxidants represent a valuable solution for the protection against oxidative stress. From the planned synthesis of a catechol‐tocopherol hybrid, we isolated a catechol‐hydroquinone hybrid through a BBr3‐mediated benzochromene‐fluoren‐1‐ol transposition.
