Carbohydrate modified polysiloxanes II. Synthesis via hydrosilation of mono-, di-and oligosaccharide allylglycosides

摘要: The synthesis of linear carbohydrate modified polysiloxanes has been successfully performed by hydrosilation functionalized and protected derivates. functionalization (allyl glycosilation) may be applied to a wide variety reducing carbohydrates. In this study, mono-, di- oligosaccharides were converted simple two-step reaction (β-acetylation allyl into active compounds, allowing the polymer analogous addition random poly[dimethyl-co-hydromethyl]siloxanes (hydrosilation). By variation Si–H amount in starting polymers, with 1.5% 56% (by weight) content prepared. At small degrees substitution remain soluble non-polar media. With increasing polymers become more polar solvents like isopropanol or methanol. A polysiloxane 29% maltose comonomeric units (56 wt.-% content) was fully water soluble.
