Deuteriumincorporation can effectively stabilize the chiral centers of drug and agrochemical candidates that hampered by rapid in vivo racemization. In this work, the synthetically challenging chiral-center deuteration of alcohols has been achieved via a single-electron umpolung reductive-deuteration protocol using benign D2O as deuterium source and mild SmI2 as electron donor. The broad scope and
