β‐Alkoxy alcohols are selectively oxidized into hemiacetal esters in a one‐pot cascade process, combining a TEMPO‐catalyzed step and a stoichiometric step with a common oxidizing reagent, mCPBA. Under a similar reaction setting, β‐alkoxy 1,2‐diols also form hemiacetal ester products, undergoing a multistep oxidative cascade transformation.
