Thiosugar nucleotide analogs: synthesis of 5'-(2,3,4-tri-O-acetyl-6-S-acetyl-6-thio-alpha-D-galactopyranosyl diphosphate).
The synthesis of a novel analog of uridine diphosphate galactose (UDP-Gal) is described. A sulfur atom was inserted into the 6-position of galactose to give uridine 5'-(2,3,4-tri-O-acetyl-6-S-acetyl-6-thio-alpha-D-galactopyranosyl diphosphate). This peracetylated thiol analogue of UDP-Gal has been synthesized in nine steps starting from methyl alpha-D-galactopyranoside in an overall yield of 3%.
