  An efficient synthesis of a hexasaccharide—the repeating unit of the exopolysaccharide from Cryptococcus neoformans serovar A

  摘要：

  A general method for the synthesis of 2-xylose or glucuronic acid branched (1 --> 3)-linked mannose oligosaccharides has been developed. As a typical example, the synthesis of the methyl glycoside Of beta-D-GlcpA-(1 --> 2)-alpha-D-Manp-(1 --> 3)-[beta-D-Xylp-(1 --> 2)-]alpha-D-Manp-(1 --> 3)-[beta-D-Xylp-(1 --> 2)-]alpha-D-Manp, the repeating unit of the exopolysaccharide from Cryptococcus neoformans serovar A, was achieved in a regio- and stereoselective manner.

  Two hexasaccharides, beta-D-Xyip-(1 --> 2)-alpha-D-Manp-(1 --> 3)-[beta-D-Xylp-(1 --> 42)-]alpha-D-Manp-(1--> 3)-[beta-D-GlcpA-(1 --> 2)-]alpha-D-Manp and beta-D-GlcpA-(1 --> 2)-[beta-D-Manp-(1 --> 3)-[beta-D-XylP-(1 --> 2)-]alpha-D-Manp-(1 --> 3)-]alpha-D-Manp, the repeating unit of the exopolysaccharide from Cryptococcus neoformans serovar A, were synthesized as their methyl glycosides in a regio- and stereoselective manner.
