    • Abstract


      The fused cyclic 𝑁-acyliminium ion generated during the imide carbonyl activation reaction of phenethylphthalimide was confirmed by single crystal X-ray diffraction. The Lewis acid assisted imide carbonyl activation methodology was successfully extended to synthesize fused tetrahydro-𝛽-carboline units from the corresponding 𝑁-indolylethylimides.
