Application

1-Naphthoic acid can be used as a reactant to prepare:
  • Perinaphthenones by dehydrative annulation with alkynes in the presence of rhodium catalyst.
  • Isocoumarin derivatives by reacting with 2-butyne via aerobic oxidative cyclization using Rh catalyst.
  • N-Methoxy-N-methyl-1-naphthalenecarboxamide (Weinreb amide) by reacting with N,O-dimethylhydroxylamine and phosphorus trichloride.
  • 1,4-Dihydro-1-naphthalenecarboxylic acid by Birch reduction.
