The protecting groups used in carbohydrate chemistry are no different from those used in normal organic synthesis, but several types are often needed for a single monosaccharide building block. One‐pot methodologies enable the preparation of building blocks in short periods have been developed. 1061 18 Selective deprotection of trityl group on carbohydrate by microflow reaction inhibiting migration of acetyl group.

The paper ends with illustrative examples of the use of protecting groups in modern synthetic carbohydrate chemistry, namely the synthesis of nitrogen containing compounds belonging to an important class of polyhydroxylated cyclic amines. Protecting groups are usually used to temporarily mask a functional group which may interfere with a certain reaction, but protecting groups in carbohydrate chemistry do more than protecting groups usually do. 0000002880 00000 n Super arming of a glycosyl donor using a molecular lever.
