The application of stereochemically defined acyclic fully substituted enolates of ketones to the enantioselective synthesis of quaternary carbon stereocenters would be highly valuable. Herein, we describe an approach leading to the formation of several new stereogenic centers through a combined metalation–addition of a carbonyl–carbamoyl transfer to reveal in situ stereodefined α,α‐disubstituted enolates
