Abstract
Alkyl 2,3-O-isopropylidene-5-O-methoxymethylfuranoside derivatives undergo selective cleavage of the 2,3-O-isopro-pylidene group, if oriented cis to the O-glycoside, in the presence of trifluoroacetic acid. Otherwise, the cleavage of the 5-O-methoxy-methyl group is favoured over the 2,3-O-isopropylidene group.
