Selective Deuteration and Tritiation of Pharmaceutically Relevant Sulfoximines

open access: yesAngewandte Chemie, Volume 137, Issue 5, January 27, 2025.
We report highly effective iridium‐catalyzed methods for the installation of hydrogen isotopes into pharmaceutically‐relevant sulfoximine‐containing structures that can be conducted selectively via exchange at C(sp2)‐ and C(sp3)‐centers. The utility of this catalytic platform has also been demonstrated through the late‐stage and single step generation ...
