Intramolecular Cyclization with Nitrenium Ions Generated from N-Chloro-N-methoxyamides in Neutral Conditions

Abstract
Intramolecular aromatic substitution by a N-chloro-N-methoxyamide group to a suitably situated aromatic ring in the molecule is performed by using anhydrous zinc acetate and nitromethane as solvent to give nitrogen heterocycles in good yield.
