Methyl 2,4,6-tri-O-benzyl-P-D-galactopyranoside (5) was obtained crystalline by way of its 3-O-ally] derivative, which was in turn obtained by ring-opening of a presumed 3,4-0-stannylene derivative of methyl p-D-galactopyranoside, followed by benzylation. Condensation of 5 with 2-methyl-(2-acetamido

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
## Abstract 13‐__O__‐β‐D‐Glucopyranosylgibberellin A~5~ β‐D‐glucopyranosyl ester (2a) was synthesized by base‐catalyzed (triethylamine) reaction of gibberellin A~5~ 13‐__O__‐β‐D‐glucopyranoside (4a) with α‐acetobromoglucose followed by mild sodium methanolate deacetylation. Structures of the gibber
