6,7-Dihydro-2-pentafluorophenyl-5H-pyrrolo[2,1-c]-1,2,4-triazolium tetrafluoroborate, min. 98%

Technical Notes:
1. Reagent used in the highly enantio- and diastereoselective, catalytic intramolecular Stetter reaction.
2. Enantioselective synthesis of ß-hydroxy and ß-amino esters.
3.Organocatalytic iminium ion/carbene reaction cascade for the formation of 2,4-disubstituted cyclopentenones . 4. Synthesis of allo- and epi-lnositol via the NHC-catalyzed carbocyclization of carbohydrate-derived dialdehydes.
