The present invention is concerned with the synthesis of new carbamates derived from monosaccharides or disaccharides and their precursors. These compounds may be used as surface-active agents or co-surface-active agents of yolk phospholipids or Pluronic F-68 in preparing emulsions of fluorocarbons and other compounds. The compounds in accordance with the invention can be represented by the general formula: RFC(O)(CH2)nNHC(O)-SUGAR in which the sugar residue is connected at position C-6 and can be, for example, a glycosyl, alpha -methylglucopyranosyl, beta -methylglucopyranosyl, galactosyl, alpha -methylgalactopyranosyl, beta -methylgalactopyranosyl, mannosyl, lactosyl or gentiobiosyl group. The symbol RF represents a linear or branched perfluoroaliphatic chain, preferably with 1 to 10 carbon atoms, and n is preferably equal to 4 or 5.

Abstract
The present invention is concerned with the synthesis of new carbamates derived from monosaccharides or disaccharides and their precursors. These compounds may be used as surface-active agents or co-surface-active agents of yolk phospholipids or Pluronic F-68 in preparing emulsions of fluorocarbons and other compounds. The compounds in accordance with the invention can be represented by the general formula: RFC(O)(CH2)nNHC(O)-SUGAR in which the sugar residue is connected at position C-6 and can be, for example, a glycosyl, alpha -methylglucopyranosyl, beta -methylglucopyranosyl, galactosyl, alpha -methylgalactopyranosyl, beta -methylgalactopyranosyl, mannosyl, lactosyl or gentiobiosyl group. The symbol RF represents a linear or branched perfluoroaliphatic chain, preferably with 1 to 10 carbon atoms, and n is preferably equal to 4 or 5.
