Synthesis of new tetracyclic azaheteroaromatic cores via auto-tandem Pd-catalyzed and one-pot Pd- and Cu-catalyzed double C–N bond formation

Synthesis of benzo[4,5]imidazo[1,2-a]quinoxalines by I2-mediated sp3 C–H amination

Benzo[4,5]imidazo[1,2-a]quinoxalines were synthesized by I₂-mediated sp³ C–H amination under transition-metal free conditions in an efficient and scalable fashion.

Applications of Palladium-Catalyzed C-N Cross-Coupling Reactions

Pd-catalyzed cross-coupling reactions that form C–N bonds have become useful methods to synthesize anilines and aniline derivatives, an important class of compounds throughout chemical research. A key factor in the widespread adoption of these methods has been the continued development of reliable and versatile catalysts that function under operationally simple, user-friendly conditions. This review provides an overview of Pd-catalyzed N-arylation reactions found in both basic and applied chemical research from 2008 to the present. Selected examples of C–N cross-coupling reactions between nine classes of nitrogen-based coupling partners and (pseudo)aryl halides are described for the synthesis of heterocycles, medicinally relevant compounds, natural products, organic materials, and catalysts.

Transformation of masked benzyl alcohols to o-aminobenzaldehydes through C–H activation: a facile approach to quinazolines

A decorating strategy has been developed for the synthesis of important synthetic units from benzyl alcohols through C–H functionalization.
