route for the synthesis of trifluoromethyl- or sulfonyl-substituted β-enamino ketones. Mechanistic studies reveal a dual role for the silver catalyst and provide insight into the nature of the migration by demonstrating the positional influence of arene substituents on arene migratory aptitude. By in situ generation of the key migration substrate from readily available precursors, this method offers a novel

zwitterion, and the subsequent selective annulation afforded α-amino cyclobutanone. Features such as readily available substrates, mild reaction conditions, a time-saving procedure, excellent functional group compatibility, and valuable transformations of the products qualified this unique protocol as an efficient tool for the synthesis of strained cyclic compounds.
