title: [Synthesis of oligosaccharide fragments of mannan from Candida albicans cell wall and their BSA conjugates].
abstract: 3-Aminopropyl glycosides of alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyra-nosyl-(1-->2)-alpha-D-mannopyranose, alpha-D-mannopyranosyl-(1-->3)-alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyranosyl-(l -- 2)-alpha-D-mannopyranose, and alpha-D-mannopyranosyl-(1-->2)-[alpha-D-mannopyranosyl-(1-->3)]-alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyranose were efficiently synthesized starting from ethyl 2-O-acetyl(benzoyl)-3,4,6-tri-O-benzyl-l-thio-alpha-D-mannopyranoside, ethyl 4,6-di-O-benzyl-2-O-benzoyl-1-thio-alpha-D-mannopyranoside, ethyl 4,6-di-O-benzyl-2,3-di-O-benzoyl-l-thio-alpha-D-mannopyranoside, and 2,3,4,6-tetra-O-benzoyl-alpha-D-mannopyranosyl bromide. The oligosaccharide chains synthesized correspond to the three structural types of side chains of mannan from Candida albicans cell wall. A conjugate of the third pentasaccharide with bovine serum albumin was prepared using the squarate method.
