A mild method for the deborylation deuteration of arylboronic acids with D2O, mediated by the synergistic combination of a thiol, a Lewis base, and photoredox catalysis, is reported. This reaction showed a broad substrate scope, excellent deuterium incorporation, and functional group tolerance. Therefore, this method is practical for the site-selective D-labeling of bioactive molecules and drug molecules

We have developed a catalytic, non-spontaneous dehalogenation process for the deuteration of aryl iodides using BaTiO3 as a catalyst. This method achieves high levels of deuterium incorporation using only 2.0 equivalents of D2O, which additionally acts as an electron donor. Furthermore, deuteration enhances the biological activity of D-ipriflavone, markedly inhibiting osteoclast differentiation.
我们开发了一种使用 BaTiO 3作为催化剂进行芳基碘化物氘化的催化非自发脱卤工艺。该方法仅使用 2.0 当量的 D 2 O 即可实现高水平的氘掺入,D 2 O 还充当电子供体。此外,氘化增强了D-ipriflavone的生物活性,显着抑制破骨细胞分化。
