The synthesis is described of a tritylated 1,2-O-cyanoethylidene derivative (3) of the trisaccharide alpha-D-Rha-(1----2)-alpha-D-Rha-(1----3)-D-Rha. Triphenylmethylium perchlorate-catalysed polycondensation of 3 in the presence of 6-phthalimidohexyl 2,4-di-O-benzoyl-3-O-trityl-alpha-D-rhamnopyranoside followed by deprotection afforded the 6-aminohexylglycoside of a D-rhamnan corresponding to a common
