    Regioselective hydration of α‐alkynyl esters and ketones by using a cationic NHC–AuI catalyst results in β‐keto esters and β‐diketones, respectively. Controlled release of water in acetone by aldol self‐condensation under the reaction conditions makes acetone as better solvent than 1,4‐dioxane/water for the hydration of α‐alkynyl esters having sensitive ester moieties. A cationic NHC–AuI catalyst opens the way to regioselective hydration of α‐alkynyl esters and ketones to afford β‐keto esters and β‐diketones, respectively.
