amination of unactivated, secondary C−Hbonds to form a broad range of functionalized pyrrolidines has been developed by a triiodide (I3−)‐mediated strategy. By in situ 1) oxidation of sodium iodide and 2) sequestration of the transiently generated iodine (I2) as I3−, this approach precludes undesired I2‐mediated decomposition which can otherwise limit synthetic utility to only weak C(sp3)−H bonds. The mechanism

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

The cross-coupling of C(sp3)–H and N–H represents one of the most straightforward approaches to construct saturated nitrogen-containing compounds. The additional oxidants or halogenated reagents are generally required in such processes. Herein, we developed an electrochemical oxidative intramolecularC(sp3)–Hamination of amides by employing a carbon rod anode and a platinum plate cathode in an undivided

The present invention relates to tricyclic heterocycles. These heterocyclic compounds are useful as TEAD binders and/or inhibitors of YAP-TEAD and TAZ-TEAD protein-protein interaction or binding and for the prevention and/or treatment of several medical conditions including hyperproliferative disorders and diseases, in particular cancer.
