We report the synthesis of derivatives of vitamin K3 as well as of vitamins K1 and K2 containing a different number of methyl groups in various positions in order to reduce their redox potentials and to change systematically their steric features. The long aliphatic chain of vitamins K1 and K2 is simulated by an undecyl chain or a methyl group, respectively. The redox potentials of the first reduction
我们报告了维生素K 3以及维生素K 1和K 2在不同位置含有不同数量甲基的衍生物的合成,以降低其氧化还原电位并系统地改变其空间特征。维生素K 1和K 2的脂肪族长链分别由十一烷基链或甲基模拟。通过在DMF中的循环伏安法测量第一还原步骤的氧化还原电势。这些化合物与研究维生素K依赖性酶的结构-功能关系以及研究光合作用中心的电子转移反应有关。
