Abstract

The first synthesis of 3-deoxy-3-fluoro-L-fucose is presented, which employs a D- to L-sugar translation strategy, and involves an enzymatic oxidation of 3-deoxy-3-fluoro-L-fucitol. Enzymatic activation (FKP) and glycosylation using an α-1,2 and an α-1,3 fucosyltransferase to obtain two fluorinated trisaccharides demonstrates its potential as a novel versatile chemical probe in glycobiology.
