Synthetic studies on the trisaccharide intermediate of resin glycoside merremoside H(2).
A protected trisaccharide imidate, 2,3-di-O-acetyl-4,6-O-benzylidene-beta-d-glucopyranosyl-(1-->3)-2-O-chloroacetyl-3-O-benzyl-4-isobutyryl-alpha-l-rhamnopyranosyl-(1-->4)-2-O-isobutyryl-alpha-l-rhamnopyranosyl trichloroacetimidate (1), has been synthesized by a block synthesis approach. Compound 1 can serve as a key intermediate in the total synthesis of resin glycoside merremoside H(2).
