Zusammenfassung:
Late-stage deuteration is a crucial technique in the pharmaceutical industry. Direct aromatic deuteration without the use of directing groups or transition-metal catalysts presents a substantial challenge. Now, through the integration of an interrupted Birch reduction, Liang, Xia, and co-workers have developed a photochemical protocol for the efficient hydrogen isotope exchange to incorporate deuterium into the arenes of pharmaceuticals.
