Notizen:
We have studied the fluoroalkylation of the glucal 1 and the galactal 4 with dibromodifluoromethane via the 2-C-bromodifluoromethyl-substituted glycosyl bromides 2 and 5, respectively, followed by glycosylation to the methyl β-D-glycosides 3 and 6. The bromodifluoromethyl groups in the 2 position of the compounds 3 and 6 were converted into difluoromethyl and trifluoromethyl groups, respectively, giving the fluorinated monosaccharides 7-10.
