Three phosphomethyl tocopheryl acetates: 7-phosphomethyl-β-tocopheryl acetate (IXa), 5-phosphomethyl-A-tocopheryl acetate (IXb), 5-phosphomethyl-δ-tocopheryl acetate (IXc), and their sodium salts (Xa), (Xb) have been synthesized starting from acetoxymethyl tocopheryl acetates by unequivocal way. These phosphates are of interest in a possible role of vitamin E in oxidative phosphorylation.
