Participation by Ionised Sugar Hydroxyls Base-catalysed Hydrolysis of Glycosides

3 Participation by Ionised Sugar Hydroxyls - Base-catalysed Hydrolysis of Glycosides 

Aryl glycosides, particularly those of acidic glycones, react readily in alkali, to the extent that deprotection of 2,4-dinitrophenyl glycosides is experimentally demanding. Most pathways involve participation by ionised hydroxyl groups. The effect of the aryl substituent on the rates of hydrolysis of aryl ot- and 

Aryl pentopyranosides are hydrolysed in base, but give a range of products from reaction of the reducing sugar with base.
