  • METHOD FOR PRODUCING L-FUCOSE
    Publication number: 20130245250
    Abstract: Method for producing L-fucose includes in a first aspect, a method for the preparation of L-fucose, wherein L-fucose precursors are produced from pectin and L-fucose is produced from the L-fucose precursors; in a second aspect, a method for the preparation of L-fucose from D-galacturonic acid or a salt thereof, wherein L-fucose precursors are produced from D-galacturonic acid of a salt thereof, and L-fucose is produced from the L-fucose precursors; and an L-fucose precursor as shown in Formula A, wherein R is a linear or branched chain saturated hydrocarbon group with 1-6 carbon atoms, such as methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, s-butyl, t-butyl, n-hexyl, etc., preferably a methyl group.
