: The synthesis of axially chiral compounds has attracted a great deal of attention in the recent years. Herein, an efficient and economical synthetic route has been developed for 2-(3-carbamoylpyridin-2-yl) nicotinamide pyridine salts, an axially chiral compound. The starting material 1,10-phenanthroline has been readily available and 2-(3-carbamoylpyridin-2-yl) nicotinamide pyridine salts have been obtained in moderate to good yields. This protocol features simple operation and easy scalability. In addition, the axial chirality of the products has also been preliminary studied.

In recent years, the synthesis of axially chiral compounds has received considerable attention due to their extensive application as biologically active compounds in medicinal chemistry and as chiral ligands in asymmetric catalysis. Chiral phosphoric acids are recognized as efficient organocatalysts for a variety of enantioselective transformations. In this review, we summarize the recent development of chiral phosphoric acid-catalyzed synthesis of a wide range of axially chiral biaryls, heterobiaryls, vinylarenes, N-arylamines, spiranes, and allenes with high efficiency and excellent stereoselectivity.
