Description

1,2:3,4-Di-O-isopropylidene-a-D-galactopyranose, also known as diacetone-D-galactose and galactose diacetonide, is a partially protected monosaccharide building block with isopropylidene groups on the 1,2 and 3,4 hydroxyls. The 6-hydroxyl is unprotected and able to undergo a variety of chemical transformations, such as glycosylation acting as a glycosyl acceptor to form 1,6-linked disaccharides.
