formed in vivo in the human brain as a consequence of an increased oxidative stress, and they could be valuable biomarkers of the neuronal oxidative stress. In this paper, an enantioselective stereodivergent approach to two key neurofuran precursors, belonging to the AC and ST classes, has been developed starting from a single achiral precursor, the meso-diol 11. The absolute configuration of the THF
神经呋喃是由于氧化应激增加而在人脑中体内形成的,它们可能是神经元氧化应激的重要生物标志物。在本文中,从单一的非手性前体中消旋二醇11开始,开发了一种对映体选择性立体发散方法,用于两种主要的AC和ST类神经呋喃。通过分别使用(S,S)-L1和(R,R)-L2配体的Pd催化的不对称烯丙基烷基化来确保THF核的绝对构型。
