1,1′-Binaphthylazepine-based ligands for asymmetric catalysis. Part 1: Preparation and characterization of some new aminoalcohols and diamines
摘要:
Starting from (S)-1.1 ' -binaphthol, a series of ten novel enantiopure 1.1 ' -binaphthylazepine-based aminoalcohols and diamines 1a-1j were efficiently prepared and fully characterized. These derivatives, having either only an atropisomeric bridged-binaphthyl backbone or an additional stereogenic carbon center, can be interesting ligands for asymmetric catalysis.
