Iridium-Catalyzed C–H Amination with Anilines at Room Temperature: Compatibility of Iridacycles with External Oxidants
摘要:
Described herein is the development of an iridium-catalyzed direct C-H amination of benzamides with anilines at room temperature, representing a unique example of an Ir catalyst system that is compatible with external oxidants. Mechanistic details, such as the isolation and characterization of key iridacycle intermediates, are also discussed.

Described herein is the development of Cp*Ir-(III)-catalyzed direct arene C-H amination using alkylamines as an amino source. This C-N bond formation showcases a notable example of cross-dehydrogenative coupling to install an amino functionality at the ortho-position of benzamide substrates. Mechanistic studies including the isolation of an amine-bound iridacyclic intermediate along with a set of chemical oxidations demonstrated the Ir-catalyzed inner-sphere C-H amination with primary alkylamines for the first time.

A TRPM8 antagonist is provided that comprises the following the formula (I) described herein. In the formula (I), R1 is selected from a cycloalkyl, a bicycloalkyl, or a tricycloalkyl group. Each R1 group has 5 to 12 carbon atoms. Further, each R1 group is optionally substituted with an alkyl group having 1 to 5 carbons atoms or with a cycloalkyl group having 4 to 12 carbon atoms, and each R1 group is optionally saturated or partially unsaturated. Methods for treating pain are further provided and comprise administering to a subject in need thereof an effective amount of a TRPM8 antagonist comprising the formula (I).
