It is shown that the previously found rearrangement can be applied on the nitrile 4 (X = CN) when the anhydride used possesses only one α-hydrogen atom. Refluxing of this nitrile with isobutyric anhydride in the presence of triethylamine leads to the expected rearrangement product 5 (X = CN). Making use of the same anhydride, the esters 4 (X = COOR) are converted into esters 5 (X = COOR).
