We developed a method for the preparation of (diacetoxyiodo)-2-(N-alkylamido)benzene as an aniline-type hypervalent iodine(III). We also achieved direct cyclizations via C?H bond abstraction, such as the Hofmann-L?ffler-Freytag reaction, a direct amination, and a direct lactonization, using the aniline-type hypervalent iodine(III) to obtain corresponding products in high yields.

Radical cyclization approach to spirocyclohexadienones
Gonzalez-Lopez De Turiso, Felix,Curran, Dennis P.
, p. 151 - 154 (2007/10/03)
(Chemical Equation Presented) Cyclization of an aryl radical at the ipso position of a p-O-aryl-substituted acetamide or benzamide generates oxindoles or quinolones bearing spirocyclohexadienone rings. This versatile reaction is applied to formal synthese
