Electrophilic ipso-iodocyclization of N-benzyl-N-(1-naphthyl)propiolamides: synthesis of complex polycyclic lactams†
Abstract
An intramolecular electrophilic ipso-iodocyclization of N-benzyl-N-(1-naphthyl)propiolamides combined with the Friedel–Crafts-type reaction for the synthesis of complex polycyclic lactams is reported. The resulting iodinated cyclization product can provide a very useful handle for further structural manipulation.
