The invention relates to a method for preparing F-Dopa and
18
F-Dopa and intermediates that are useful in the method. The invention is a method that synthesizes F-Dopa and
18
F-Dopa in good yield with high enantiopurity without the need for further transformations. The method includes the step of reacting a benzaldehyde derivative with a phosphonic acid derivative to produces an olefin intermediate that can be asymmetrically hydrogenated to produce the desired enantiomer.
这项发明涉及一种制备F-Dopa和18F-Dopa以及在该方法中有用的中间体的方法。该发明是一种合成F-Dopa和18F-Dopa的方法,其产率高,对映纯度高,无需进一步转化。该方法包括将
苯甲醛衍
生物与
