METHOD OF PRODUCING GALACTOOLIGOSACCHARIDE, AND INTERMEDIATE THEREOF

PROBLEM TO BE SOLVED: To provide a method of producing a galactooligosaccharide that may cause the onset of allergic reaction, and an intermediate thereof. SOLUTION: A method of producing a galactooligosaccharide represented by the general formula (1) comprises addition of the 1-position of protected galactobiose to the 6-position hydroxy group of protected lactose of formula (5), and subsequent deprotection of a hydroxy group protecting group.

Regioselective removal of the anomeric O-benzyl from differentially protected carbohydrates

A mild, regioselective deprotection of the anomeric O-benzyl from multi-functionally protected carbohydrates via catalytic transfer hydrogenation is described. The protocol is tolerant of O-benzyl and O-benzylidene protections at non-anomeric positions, g

Inhibitory effects of Ellagi- and gallotannins on rat intestinal α-glucosidase complexes

The clove ellagitannins and their related polygalloylglucoses inhibited maltase activity of rat intestinal α-glucosidases. The structure-activity relationship study of those galloylglucoses, varying the extent of galloylation on the glucose core, with the
