phenols, indoles and other heterocycles, using inexpensive D2O under hydrogen pressure. This methodology represents an easily scalable deuteration (demonstrated by the synthesis of deuterium-containing products on the kilogram scale) and the air- and water-stable catalyst enables efficient labelling in a straightforward manner with high quality control.
同位素标记,特别是氘代,是开发新药的重要工具,特别是用于代谢物的鉴定和定量。为此,已经开发了许多有效的方法,允许小规模合成选择性氘代化合物。由于氘代化合物作为活性药物成分的发展,人们对可扩展的氘代方法越来越感兴趣。工业环境中大规模氘标记方法的开发需要可靠、稳健和可扩展的技术。在这里,我们展示了通过将纤维素与丰富的铁盐结合制备的纳米结构铁催化剂,允许使用廉价的 D2 O 在氢气压力下。这种方法代表了一种易于扩展的氘化(通过在千克规模上合成含氘产品来证明),并且空气和水稳定的催化剂能够以直接的方式进行有效的标记,并具有高质量的控制。
Selective deuteration of (hetero)aromatic compounds via deutero-decarboxylation of carboxylic acids
mild and highly selective protocol for the monodeuteration of a variety of arenes and heteroarenes is presented. Catalytic amounts of Ag(I) salts in DMSO/D2O are shown to facilitate the deutero-decarboxylation of ortho-substituted benzoic and heteroaromatic α-carboxylic acids in high yields with excellent levels of deuterium incorporation.
