摘要
A low-water organic solvent two-phase system suitable for glycosylation of hydrophobic substrates is described. Almond β-glucosidase adsorbed on polymeric supports has been shown to catalyse alkyl-β-glucoside synthesis via a transferase reaction or through direct condensation of the glucosidic bond. High concentrations of glucosyl donors were present in the aqueous phase, while water-immiscible primary alcohols, which form the organic phase, served as acceptors of glucose. Reaction yield appeared to be thermodynamically controlled. The influence of various support materials, glucosyl donors, and glucosyl acceptors on reaction rate and product yield was investigated. © 1990.
