A method of producing alpha-tocotrienol quinone or a stereoisomer thereof, the method comprising selective opening of alpha-tocotrienol chroman to alpha-tocotrienol quinone in the presence of non-alpha tocotrienol chromans by oxidizing alpha-tocotrienol with a metal salt oxidizing agent, wherein the stoichiometric ratio of metal salt oxidizing agent/alpha-tocotrienol is at least 4:1 and wherein said metal oxidizing agent is added in sequential additions, in order to reduce oxidation of any amounts of non-alpha tocotrienol chromans that might have been present in the starting alpha-tocotrienol chroman material. This process uses conditions favoring oxidation rates of the alpha tocotrienol chroman vs. the non-alpha tocotrienol chromans.
一种生产α-生育三烯酚醌或其立体异构体的方法,该方法包括通过用金属盐氧化剂氧化α-生育三烯酚,在存在非α-生育三烯酚色烷的情况下,选择性地将α-生育三烯酚色烷开成α-生育三烯酚醌,其中金属盐氧化剂/α-生育三烯酚的化学计量比至少为4:其中,金属盐氧化剂/α-生育三烯酚的化学计量比至少为 4:1,并且所述金属氧化剂以顺序添加的方式加入,以减少起始α-生育三烯酚色烷材料中可能存在的任何数量的非α-生育三烯酚色烷的氧化。该工艺使用的条件有利于α-生育三烯酚色满与非α-生育三烯酚色满的氧化率。
