Abstract
Deuteration of bioactive molecules is gaining more and more attention, especially
after the approval of the first deuterated drug (Austedo™) by the US Food and Drug
Administration (FDA). Not only is deuteration important for drug development, the
amount of deuterium in a molecule is critical for the production of standards in mass
spectrometry and the selectivity of the deuteration is mandatory for NMR applications.
Very frequently, the molecules involved in these applications contain several heteroatoms.
It has been demonstrated that oxygen-, nitrogen-, and more recently, sulfur-containing
molecules can be easily deuterated at the α position leading to high deuterium incorporation.
In this review we will focus our attention on the historical background and the recent
progress made on heteroatom-directed deuteration, with particular attention on the
catalysts and the mechanisms that drive such transformations.
