The redox behavior of "active aldehydes" 1- derived from 3-benzylthiazolium salts and simple aldehydes in the presence of a base has been examined with low-temperature cyclic voltammetry and EPR spectroscopy. The highly negative oxidation potentials of 1- and the spin distribution of the intermediate radicals 1. indicate that the active aldehyde can act as an efficient electron mediator in thiamin-dependent
“活性醛” 1所述的氧化还原行为-从3- benzylthiazolium盐和在碱的存在下简单的醛衍生的已研究了与低温循环伏安法和EPR谱。要求1所述的高度负的氧化电势-和中间基团1的自旋分布。表明活性醛可以在硫胺素依赖的酶氧化还原体系中充当有效的电子介体。
