General description

5-Phenyl-1,3-cyclohexanedione is a 1,3-diketone.[1] Reaction of 5-phenyl-1,3-cyclohexanedione with N-substituted isatins in pyrindine has been investigated.[2]

Application

5-Phenyl-1,3-cyclohexanedione may be used:
  • in the synthesis of hexahydrobenzo[a]phenanthridin-4-one derivatives via condensation with N-arylmethylene-2-naphthylamines[3]
  • in the preparation of benzophenanthridine derivatives[1]
  • in the preparation of iodonium betaine[4]
  • in the synthesis of various 2H-pyrans by iodine-catalyzed reactions[5]
