摘要：

Syntheses are described of two trisaccharides, 2-(p-trifluoroacetamidophenyl)ethyl O-(beta-D-xylopyranosyl)-(1-->2)-O-(alpha-D-mannnopyranosyl)-(1-->3) alpha-D-mannopyranoside (10) and 2-(p-trifluoroacetamidophenyl)ethyl O-(alpha-D-mannopyranosyl)-(1-->3)-[O-(beta-D-xylopyranosyl)-(1-->2)]-alpha-D-mannopyranoside (12), and of the tetrasaccharide 2-(p-trifluoroacetamidophenyl)ethyl O-(beta-D-xylopyranosyl)-(1-->2)-O-(alpha-D-mannno-pyranosyl)-(1-->3)-[O-(beta-D-xylopyranosyl)-(1-->2)]-alpha-D-mannopyranoside (15). These correspond to parts of the repeating unit of the major structure of the capsular polysaccharide of Cryptococcus neoformans serogroup A depicted below: [GRAP
