Abstract Our studies are presented to replace alcohols as solvents in reverse hydrolytic reactions catalyzed by immobilized β-glucosidase to synthesize O -substituted β- d -glucopyranosides in preparative-scale. We found that 1,2-diacetoxyethane is a suitable solvent and O -alkyl or aryl β- d -glucosides were synthesized in moderate yields (after isolation 12–19%). In these reactions proportion of glucose and glucosyl acceptor hydroxy compounds was 1:20. We suggest that 1,2-diacetoxyethane can… Expand
