An efficient avenue for the facile and atom-economic synthesis of (1H)-isochromen-1-imines has been developed, and a broad spectrum of substrates can participate in the process effectively to produce the desired products in good yields. Significantly, this is the first report of the synthesis of (1H)-isochromen-1-imines that involves a silver(I)-catalyzed, regiocontrolled intramolecular addition of
