and bis(aminomethylated) β-, γ- and δ-tocopherol were then subsequently transformed into the corresponding tocopherols (α- and β-tocopherol) by reductive deamination. As an alternative to classical catalytic hydrogenation in the last step, efficient laboratory protocols using complex hydrides have been derived and applied to the preparation of labelled vitamin E compounds.(© Wiley-VCH Verlag GmbH &
在改进的条件下,使用衍生自仲胺和多聚甲醛的曼尼希试剂进行氨基甲基化已被用于将非 α-生育酚同系物转化为 α-生育酚,这是生物学上最重要的维生素 E 化合物。随后通过还原脱氨基作用将单和双(氨基甲基化)β-、γ-和δ-生育酚转化为相应的生育酚(α-和β-生育酚)。作为最后一步经典催化氢化的替代方法,使用复合氢化物的高效实验室方案已经推导出并应用于制备标记的维生素 E 化合物。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007 )
