Axially chiral compounds widely occur in natural products, biologically active molecules, ligands, and catalysts, and their efficient and enantioselective synthesis is highly desirable. Herein, we report a novel method for the atroposelective construction of axially chiral N-aryl benzimidazoles with chiral phosphoric acid as the organocatalyst via reaction of N1-(aryl)benzene-1,2-diamines with multicarbonyl compounds. The present method provided the target products in high yields (up to 89percent) with excellent enantioselectivity (up to 98percent ee).

Palladium-catalyzed oxidative coupling of 2-vinylanilines and isocyanides constitutes a direct, facile, and efficient approach to 2-aminoquinolines. The procedure, employing palladium acetate and silver carbonate, is attractive in terms of assembly efficiency, functional group tolerance, and operational simplicity. A variety of 2-aminoquinolines were prepared in good to excellent yields.
One-pot ring-closing metathesis/1,3-dipolar cycloaddition through assisted tandem ruthenium catalysis: Synthesis of a dye with isoindolo[2,1-a]quinoline structure

The one-pot tandem reaction of N-alkyl-N-allyl-2-vinylaniline derivatives with benzo- or naphthoquinones and a ruthenium-alkylidene catalyst leads to isoindolo[2,1-a]quinolines in a variety of colors, which can be altered by exchanging the substituent on the core heterocycle (see scheme). This reaction offers a new synthetic method for π-conjugated small molecules from simple aniline derivatives. Copyright
