A 6-O-o-nitrobenzyl methylglucoside and methylmannoside were synthesized by
reacting 4,6-O-o-nitrobenzylidene acetals with triethylsilane and boron tr
ifluoride etherate, A 2,6-dl-O-o-nitrobenzyl and a 3,6-di-O-o-nitrobenzyl m
ethylmannoside were obtained from a 2,3:4,8-di-O-o- nitrobenzylidene methyl
mannoside by the same method, The photolabile sugars obtained were deprotec
ted by irradiation at 350 nm to afford methylglycosides..
