(11aS)-3,7-Bis[3,5-bis(trifluoromethyl)phenyl]-10,11,12,13-tetrahydro-5-hydroxy-diindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocin 5-oxide

Reaction

1. Organocatalytic asymmetric multicomponent reactions of aromatic aldehydes and anilines with β-ketoesters: facile and atomeconomical access to chiral tetrahydropyridines.
2. Pd(0)-catalyzed tandem deprotection/cyclization of tetrahydro-β-carbolines on allenes: application to the synthesis of indolo[2,3-α]quinolizidines.
3. Enantioselective synthesis of benzazepinoindoles bearing trifluoromethylated quaternary stereocenters, catalyzed by chiral spirocyclic phosphoric acids.
