Selective deprotection of photolabile anomeric 2-nitrobenzyl acetals was achieved using continuous flow photo-reactor (UV radiation at 355 nm) in methanol-water. Various protecting groups such as acetyl, benzyl, benzoyl, benzylidine, TBS, etc. were found to be highly stable during the photolysis.

Oligosaccharide compound and its manufacture and its intermediate
-
Paragraph 0237; 0238; 0239, (2018/04/14)
The purpose of the present invention is to provide an oligosaccharide with high versatility that can produce a protected sulfate oligosaccharide that can become a manufacturing intermediate of polysulfated hyaluronic acid, and to provide a manufacturing method therefor and an intermediate thereof. Position 2 amino groups in glucosamine, galactosamine, and the like can react with saccharide receptors having an electron attracting group such as glucuronic acid and protected sulfate groups, by using a saccharide donor protected by a specific protective group.
