Abstract

benzylation of poly01 compounds2 has made a significant contribution to the advance of carbohydrate chemistry. The few known examples of regioselective de-0-benzylation include that of perbenzylated methyl lyxoside by Grignard reagent: perbenzylated methyl ribofuranoside with tin tetrachloride: and perbenzylated 1, 6-anhydrohexoses catalyzed by palladium-carbon5 We describe here simple and highly regioselective de-0-benzylations ...
