Abstract:
α‐Tocopherol wss reacted with an alkylperoxyl radical at 37°C in ethanol. 2,2′‐Azo bis (2,4‐dimethylvaleronitrile) was used to generate the alkylperoxyl radicals. The reaction products of α‐tocopherol were isolated by reverse‐phase and normal‐phase high performance liquid chromatography, and their structures were characterized by infrared, ultraviolet, 1 H and 13 C nuclear magnetic resonances and mass spectrometry. They were 8a S ‐hydroperoxy‐α‐tocopherone, 8a R ‐hydroperoxy‐α‐tocopherone, a mixure of 7,8‐epoxy‐8a S ‐ethoxy‐α‐tocopherone, and 7,8‐epoxy‐8a R ‐ethoxy‐α‐tocopherone, 8a S ‐(1 R ‐cyano‐1,3‐dimethyl)butylperoxy‐α‐tocopherone, 8a S ‐(1 S ‐cyano‐1,3‐dimethyl)butylperoxy‐α‐tocopherone, a mixture of 8a R ‐(1 S ‐cyano‐1,3‐dimethyl)butylperoxy‐α‐tocopherone and 8a R ‐(1 S ‐cyano‐1,3‐dimethyl)butylperoxy‐α‐tocopherone, 4a R ,5 S ‐epoxy‐8a S ‐ethoxy‐α‐tocopherone, 4a S ,5 R ‐epoxy‐8a S ‐ethoxy‐α‐tocopherone and 4a R ,5 S ‐epoxy‐8a R ‐ethoxy‐α‐tocopherone.
