Participants

Reaction Steps

To a solution of 0.400 g of (3R,4R)-4-methylsulfonyl-3-tritylamino-2-oxoazetidine in 2 ml of DMF is added 0.590 g of tetra-n-butylammonium fluoride, and the mixture is stirred for 30 minutes at room temperature. To the reaction mixture are added ice-water and ethyl acetate. The ethyl acetate layer is separated and washed with water, followed by concentration. The residue is purified on a silica-gel column (ethyl acetate:n-hexane=1:1) to give 0.282 g of (3R)-4-fluoro-3-tritylamino-2-oxoazetidine.
