Allofuranoside, methyl 6-deoxy-2,3-0-isopropylidene

In a number of reactions on furanose derivatives, steric restraints interfere with anhydro-ring formation. 6-Deoxy-2,3-0-isopropylidene-5-O-tosyl-L-mannofuranose is readily converted by sodium methoxide into methyl 6-deoxy-2,3-0-isopropylidene-/3-D-allofuranoside. In this... 

Treatment of methyl 6-deoxy-2,3-0-isopropylidene-5-0-p-tolylsulfonyl-/3-D-allofuranoside (100) with alkoxides in hot alcohol, or with hot soda-lime caused the formation of methyl 5,6-dideoxy-2,3-0-isopropylidene-j8-D-eri/[Pg.111]
