Abstract Partial hydrolysis of allyl 2,3:4,6-di- O -isopropylidene-α- d -mannopyranoside gave allyl 2,3- O -isopropylidene-α- d -mannopyranoside which was converted into allyl 2,3- O -isopropylidene-α- d -rhamnopyranoside by reduction of the 6- O -tosyl derivative with lithium aluminium hydride. Condensation of allyl 2,3- O -isopropylidene-α- d -rhamnopyranoside with 2,4-di- O -acetyl-3,6-di- O -methyl-α-
