Modular Chiral N-Heterocyclic Carbene Ligands for the Nickel-Catalyzed Enantioselective C-H Functionalization of Heterocycles

N-Heterocyclic carbenes (NHCs) are the ligands of choice in a large variety of transformations entailing different transition metals. However, the number and variety of chiral NHCs suitable as stereo-controlling ligands in asymmetric catalysis remains limi ...

Generation of Heteroatom Stereocenters by Enantioselective C-H Functionalization

Nicolai Cramer, Johannes Diesel

C-H functionalization has been established as an efficient way to generate molecular complexity. The formation of stereogenic carbon atoms by asymmetric C-H functionalization has seen tremendous progress over the past decade. More recently, the direct cata ...

A Bulky Chiral N‐Heterocyclic Carbene Nickel Catalyst Enables Enantioselective C−H Functionalizations of Indoles and Pyrroles

Nicolai Cramer, Daria Grosheva, Johannes Diesel, Shota Kodama

An enantioselective nickel(0)-catalyzedC  Hfunc- tionalization of indoles and pyrroles that does not require the typical Lewis basic directing groups is disclosed. The reaction provides access to valuable tetrahydropyridoindoles and tetrahydroindolizines ...
