Abstract
We disclose here a novel electrophilic fluorinating reagent, N-fluoro-(3,5-di-tert-butyl-4-methoxy)benzenesulfonimide (NFBSI) as a sterically demanding analogue of popular fluorinating reagent, N-fluorobenzenesulfonmide (NFSI). NFBSI improves the enantioselectivity of the products as much as 18% for the cinchona alkaloid-catalyzed enantioselective fluorination of silylenol ether compared to the use of NFSI.
