New phenyl 6,4'-substituted-1-thio-β-maltosides, building blocks for the synthesis of linear and branched malto-oligosaccharides

Motawia,Larsen,Olsen,Moller

, p. 1547 - 1556 (2007/10/03)

An efficient strategy to synthesize a number of new phenylthio-maltoside derivatives in yields from 55 to 95% is described. These derivatives can be used as suitable building blocks for stepwise synthesis of starch derived malto-oligosaccharides.
