Abstract
A synthetically convenient approach for the direct α‐deuteration of amides is reported. This mechanistically unusual process relies on a retro‐ene‐type process, triggered by the addition of deuterated dimethyl sulfoxide to a keteniminium intermediate, generated through electrophilic amide activation. The transformation displays broad functional‐group tolerance and high deuterium incorporation.
