Deuterated analogues of α- and γ-CEHC, main urinary and plasma metabolites of vitaminE, can be traced and accurately determined quantitatively by MS in complex matrices. In that regard, here we report the first synthesis of rac-[D3]-γ-CEHC together with a simple route to 7a,8a-[D2]-γ-CEHC through the set up of efficient procedures for the preparation of the corresponding deuterated hydroquinone building
