Abstract
Acidic treatment of the hydroxyisoindolinone issued from the reaction of N-benzyl protected phthalimide with the anion of N,N dibenzylamide has led to an unexpected rearrangement. The final structural constitution and E-stereochemistry of the resulting phthalide incorporating enelactone and enamide functionalities have been unambiguously established by X-ray diffraction analysis.
