Abstract The α → β isomerization of hetaryl analogues of benzoins occurring in basicmedia on heating is a convenient preparative way to obtain hydroxymethylcarbonyl‐substituted derivatives of π‐excessive heterocycles. The reaction is favored by increased catalyst basicity, solvent polarity, and the electron‐donor ability of a hetaryl residue. At room temperature, oxidation to hetaryl analogues of
