Abstract

The electrophilic cyclization of 2-(1-alkynyl)benzamides affords high yields of cyclic imidates, instead of the previously reported isoindolin-1-ones, where cyclization proceeds on the oxygen of the carbonyl group rather than the nitrogen of the amide functionality. X-ray crystallography and spectroscopic techniques have been used to characterize the products. A correction is hereby provided in order to rectify the previous misassignment of structure.
