The synthesis of a novel uridine diphosphate galactose (UDP-Gal) analog, (UDP-2,3,6-tri-O-acetyl-4-S-acetyl-4-thio-alpha-D-galactopyranose) (10) is described. Compound 10 contains a sulfur in the place of oxygen at the 4-position of the galactose moiety. Compound 10 represents a protected form of a novel sugar nucleotide analog that can potentially be used during chemoenzymatic synthesis to modify complex oligosaccharides.

D009844	Oligosaccharides	Carbohydrates consisting of between two (DISACCHARIDES) and ten MONOSACCHARIDES connected by either an alpha- or beta-glycosidic link. They are found throughout nature in both the free and bound form.	Oligosaccharide
D009942	Organometallic Compounds	A class of compounds of the type R-M, where a C atom is joined directly to any other element except H, C, N, O, F, Cl, Br, I, or At.

D005690	Galactose	An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.

D013455	Sulfur	An element that is a member of the chalcogen family. It has an atomic symbol S, atomic number 16, and atomic weight [32.059; 32.076]. It is found in the amino acids cysteine and methionine.	Sulfur-16,Sulfur 16
D014531	Uridine Diphosphate Galactose	A nucleoside diphosphate sugar which can be epimerized into UDPglucose for entry into the mainstream of carbohydrate metabolism. Serves as a source of galactose in the synthesis of lipopolysaccharides, cerebrosides, and lactose.
