a diverse 71-member library of multisubstituted cyclic imidates is described. The key intermediates, 3-iodomethylene-containing cyclic imidates, are readily prepared in good to excellent yields by the palladium/copper-catalyzed cross-coupling of various o-iodobenzamides and terminal alkynes, followed by electrophilic cyclization with I2. These cyclic imidates were further functionalized by palladium-catalyzed

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
