Regioselective C-deuteration of a series of Endocyclic enolates (derived from cyclic aryl ketones) was efficiently achieved by quenching the corresponding “base-free” enolate in the presence of a suitable deuterium source. We discuss the structural nature of the deuterium donor and comment on the use of additives within this deuteration step.
