L-Fucose (I) is converted successively to its methyl glucoside (II), the 3,4-O-isopropylidene derivative (III), the 2-O-acetyl derivative (IV), the 2-O-acetyl-L-methylfucoside (V), the tosylate (VI), the 4-O-benzyl derivative (VII) and finally, through various steps, the 3,4-O-diacetyl-2,6-dideoxy-2-fluoro-alpha-L-talopyranosyl bromide (VIII). The condensation of (VIII) with daunomycinone (IX) gives the daunomycin derivative (X), which is converted to the isopropylidene derivative (XI). The bromination of (XI) affords the bromo derivative (XII).
