What is Synthesis of benzyl 6-O-benzoyl-3,4-O-isopropylidene-β-D-galactopyranoside and of 2-O-α-L-fucopyranosyl-D-galactose about?

## IN-lRODUCTlON The O-L-fucosyl-( l-\*2)-D-galactose sequence appears to be of wide distribution in Nature. The disaccharide 2-U-C+L-fucopyranosyl-~galactose (1) has been isolated from milk oligosaccharides', and from blood-group substances2 where it Serves as an important antigenic determinant 2-4. More recently, the trisaccharide 0-a-r\_.-fucopyranosyl-(l~2)-U-~-~galactopyranosyl-(l~4)-2-acetamido-2-deoxy-~-galactitol wasisolated from porcine submaxillary glycoproteins, and it has been suggested that the above fucosylgalactose linkage is a very general one that may be present in a wide variety of gtycoproteins 5. The synthesis of the disaccharide 1 has therefore been undertaken, by using the techniques applied for the preparation of the related ~-U-CC-Lfucopyranosyl-L-fucose6. RESULTS AND DISCUSSION
