Iridium-Catalyzed Direct C–H Amination with Alkylamines: Facile Oxidative Insertion of Amino Group into Iridacycle
摘要:
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.

and 14 ketones. In our ongoing efforts in preparing tool compounds for investigating and controlling the biosynthesis of phenazines, we recognized the limitations of existing protocols for C–N bond formation of electron-deficient anilines when usingreductiveamination. After extensive optimization, we have established three robust and scalable protocols for the reductiveamination of ketones with electron-deficient
catalyzed procedure for the N-arylation of simple aliphatic amines, amino alcohols and amino acids in pure water have been developed. A variety of substituted aryl iodides, bromides and electron-deficient chlorides were found to be applicable, and 1,2-disubstituted benzimidazoles could be prepared easily by a cascade amination/condensation process in this catalyticsystem.

Cu/Cu(2)O-catalyzed reaction is carried out in 2-ethoxyethanol or ethylene glycol diethyl ether and does not require the use of strong base or other additives. This procedure eliminates the need for acid protection, tolerates a wide range of functional groups and provides aromatic and aliphatic amines and sulfides in 81 to 99% yield.

Ligand-free iron/copper cocatalyzed cross-coupling reactions of arylhalides with amines were carried out to provide the corresponding coupling products in good yields. It is worth noting that the method displays a broad substrate scope, and is convenient, rapid, low-cost and environmentally friendly.
