Aniline-Type Hypervalent Iodine(III) for Intramolecular Cyclization via C-H Bond Abstraction of Hydrocarbons Containing N- and O-Nucleophiles

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-Loffler-Freytag reaction, a direct amination, and a direct lactonization, using the aniline-type hypervalent iodine(III) to obtain corresponding products in high yields.

Automated summary

A new synthetic method was developed with the use of aniline-type hypervalent iodine(III) for direct cyclizations, resulting in high yields of the corresponding products.
