General description

α-Naphthylamine, a naphthalene substituted by an amino group is an organic dye used as a detection reagent in the synthesis of novel azo dyes.[1]

Application

1-Naphthylamine has been used in the synthesis of Pitnot-2, an inactive analog of clathrin inhibitor Pitstop 2.[2]
It can also be used as a starting material to synthesize:
  • [(S)-HY-Phos], a novel chiral phosphine-phosphoramidite ligand for use in rhodium-catalyzed asymmetric hydrogenation of various functionalized olefins.[3]
  • N-(naphthalen-1-yl)picolinamide.[4]
