Versuchsvorschrift

L-Fucose (6-deoxy L-galactose) was reduced [a composition in total of 500 ml containing L-fucose at 1% and 20 ml of the Raney-nickel catalyst] to produce L-fucitol (6-deoxy L-galactitol). FIG. 59(a) shows HPLC analysis results of L-fucose before reduction and FIG. 59(b) shows HPLC analysis results of 6-deoxy D-galactitol after the reduction. The optical rotation of 6-deoxy L-galactitol was −1.7, and FIG. 60 shows 13C NMR spectrum of 6-deoxy D-galactitol.
