-tetraacetyl-beta-D-glucopyranosyl)-3-thioglycerol as a mixture of two
diastereomers was obtained by acylation of aacetyl-beta-D-glucopyrano
syl)-3-thio-rac-glycerol with deuterium-labelled palmitoylchloride. Th
e separation by repeated crystallization from metanol and the removal
of the protecting groups gave lmitoyl-S-beta-D-glucopyranosyl-3-thio-s
n-glycerol and mitoyl-S-beta-D-glucopyranosyl-1-thio-sn-glycerol.
