Recent years have seen a remarkable surge of interest in the study of U-Lfucosyltransferases. Of these L-fucosyltransferases, the enzyme (143)~a+fucosyltransferase has attracted a great deal of clinical interest as a potential tumor marker. This enzyme catalyzes the transfer of an L-fucosyl group f

Condensation of allyl 3,4-di-O-benzyl-beta-D-xylopyranoside with 2-O-acetyl-3,4,6-tri-O-benzyl-alpha-D-galactopyranosyl chloride in dichloromethane in the presence of silver triflate gave allyl 2-O-(2-O-acetyl-3,4-6-tri-O-benzyl-beta-D-galactopyranosyl)-3,4-di-O benzyl-beta-D-xylopyranoside (7, 83%)
Halide-assisted glycosyIation, using a non-p~icipating Z-substituent (benzyl) in the glycosyl halide, was used to obtain the ~-D-gaiactosyl linkage and silver triflate promotion with a participating 2-substituent (benzoyl) was used to obtain the /3-D-galactosyl linkage in a facile synthesis of the t
