Background:

(S)-(-)-1,1' -bi2-naphthylamine is an important structural unit of some natural products, bioactive compounds, materials, chiral ligands and chiral catalysts. In the field of biological activity, natural product compounds such as (-) -Streptonigrin contain axially linked phenol and arylamine fragments and are linked by Chemicalbook's special chiral aromatic amine skeleton. This unique structure makes it an antibiotic with significant biological activity. Therefore, this family of compounds has quite good anti-cancer, anti-bacteria, fungi, nematodes, viruses and a wide range of biological activities. In catalysis, chiral aromatic amines have been widely used as powerful chiral ligands or auxiliaries in asymmetric synthesis.
