Application

5a(R),10b(S)-5a,10b-Dihydro-2-(pentafluorophenyl)-4H,6H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium tetrafluoroborate can be used as an N-heterocyclic carbene (NHC) organocatalyst in:
  • Benzoin reactions of aldehydes and total synthesis of a natural product named isodarparvinol B.
  • Synthesis of spirocyclic oxindole-dihydropyranones by reacting α-bromo-α,β-unsaturated aldehydes with isatin derivatives.
  • Synthesis of 1,4-dicarbonyl compounds through intramolecular Stetter reaction.
