[Uses]

(5aR,10bS)-5a,10b-Dihydro-2-(2,4,6-trimethylphenyl)-4H,6H-indeno[2,1-b]-1,2,4-triazolo[4,3-d]-1,4-oxazinium chloride monohydrate can be used as a catalyst:
  • In the preparation of dihydropyridinones by reacting enals or α′-hydroxyenones with vinylogous amides via aza-Claisen annulations.
  • In the oxidative coupling reactions of di(hetero)arylmethanes with enals to yield benzimidazole fused lactams.
  • In the synthesis of organosilanes by reacting enals with β-silyl enones.

[General Description]

It is an N-mesityl-substituted chiral triazolium N-heterocyclic carbene (NHC) compound. It was developed as an organocatalyst by the Bode group, for the catalytic generation of reactive species including activated carboxylates, homoenolates, and enolates.
