a synthetic FOS mixture was achieved through the selective complexation of glucose and fructose with phenyl boronicacid (PBAc) followed by ethyl-acetate extraction. The process was applied to a complexmixture of FOS obtained in an enzymatic synthesis reaction containing 40% glucose, 15.8% fructose and 35% of FOS, elimination of the sugars was achieved through 3:1 molar reactions, resulting in a levan-type

Abstract The synthesis of boronic esters of L -fucose, D -glucose, D -fructose,, and DL -glyceraldehyde is described. The structures of these compounds and appropriate derivatives, based on p.m.r. and mass-spectral data, are discussed.
