摘要：

The alpha-(1 -> 6)-linked and the alpha-(1 -> 2)-linked linear mannotetraose glycosides 3 and 4, respectively, and the branched mannopentaoside 2 [R = CH2(CH2)(2)CH2Cl] were synthesised by conventional methods in Solution, using trichloroacetimidate donors, and the products were obtained in 39%, 42% and 40%, overall yield, respectively. For comparative purposes, the same two linear tetrasaccharides were prepared by use or MPEG as a soluble polymer support, the yields being 34% and 14%, respectively. An attempted MPEG-supported synthesis of the branched pentasaccharide was unsuccessful. The merits and shortcomings of oligosaccharide syntheses on MPEG are discussed. (c) 2005 Elsevier Ltd.
