Background | (S)-(-)-1,1 '-bi-2-naphthylamine is some natural products, biologically active compounds, materials, chiral ligands and important structural units of chiral catalysts. In the field of biological activity, natural product compounds such as (-)-streptonigrin contain phenol and arylamine fragments that are chirally connected to the axis, and are connected by a special chiral aromatic amine skeleton. This unique structure makes It becomes an antibiotic with significant biological activity, so this family of compounds has a wide range of biological activities such as anti-cancer, anti-bacteria, fungi, nematodes, viruses, etc. In the field of catalysis, chiral aromatic amines have been widely used as powerful chiral ligands or auxiliaries in asymmetric synthesis. |
use | (S)-(-)-1,1 '-bi-2-naphthylamine is used in the laboratory research and development process and the chemical and pharmaceutical synthesis process. |
