An in situ generated cationic Ir‐catalyst isomerizes simple allylic silylethers into valuable, fully substituted aldehyde‐derived silylenolethers. Importantly, by judicious choice of substrate, either of the two possible stereoisomers of a given enolate derivative is accessible with complete stereoselectivity. One‐pot isomerization‐aldol and isomerization‐allylation processes illustrate the synthetic
