Immobilizing BINOL via Suzuki Reaction: Synthesis and Application in Catalytic Asymmetric Oxidation of Sulfide to Sulfoxide
摘要:
Immobilizing chiral 1,1'-bi-2-naphthol (BINOL) in one step onto polymer backbone via stable carbon-carbon bond through Suzuki reaction was achieved. The application of this immobilized chiral BINOL to the catalytic asymmetric oxidation of sulfide to sulfoxide exhibited good activity (up to 60% yield) and high enantioselectivity (up to 89% ee). The immobilized chiral catalyst was very stable and could be readily reused for over 5 times without significant loss of catalytic activity and enantioselectivity.
