Recommanded Product: (5aS,10bR)-2-(2,4,6-Trichlorophenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (5aS,10bR)-2-(2,4,6-Trichlorophenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate, is researched, Molecular C18H13BCl3F4N3O, CAS is 1214711-48-4, about N-Heterocyclic Carbene Catalyzed Asymmetric Hydration: Direct Synthesis of α-Protio and α-Deuterio α-Chloro and α-Fluoro Carboxylic Acids. Author is Vora, Harit U.; Rovis, Tomislav.
Asym. hydration of α,α-dichloro aldehydes and α-halo enals via a NHC-catalyzed redox process to yield enantioenriched α-chloro and α-fluoro carboxylic acids is described herein. The developed reaction allows for installation of an α-deuterium to give rise to enantioenriched α-deutero α-halo acids using D2O as the deuteron source.
