Reaction of p-trifluoroacetamidophenyl2,4-di-O-benzyl-a-r>-mannopyranoside with 2-0-acetyl-3,4,6-tri-O-benzyl-cy-D-mannopyranosyl chloride gave a trisaccharide derivative which was 0-deacetylated and then treated with ethyl 2,3,4tri-O-benzyl-6-O-dibenzyloxyphosphoryl-l-thio-a-D-mannopyIanoside. The
