3-(5-Tocopheryl)propionic acid (γ-tocopherol-5-propionic acid, 13) has been synthesized by a multi-step sequence involving the hetero-Diels-Alder reaction between O-methyl-C,O-bis-(trimethylsilyl)ketene acetal (10) and the ortho-quinone methide of α-tocopherol (5) as the key step. The title compound is the first 5a-substituted tocopherol that shows an oxidation behavior largely similar to α-tocopherol.
