The α→β isomerization of the hetaryl analogs of unsymmetrical benzoins on heating in basic media is a convenient preparative method for the production of α-hydroxyacyl derivatives of π-excessive heterocycles. The motivating force here for the isomerization is the formation of a thermodynamically more stable product. It was established that α→β isomerization is promoted by increase in the difference between the electron-donating characteristics of the (het)aryl residues
