Synthesis of Alkyl β -Glucosides by Transglucosylation Using Pyrococcus furiosus β -Glucosidase Immobilized onto Gelatin Gel

Synthesis of alkyl β-glucosides such as p-anisyl β-D-glucopyranoside, phenethyl β-D-glucopyranoside, salidroside, cinnamyl β-D-glucopyranoside, citrusin D, 3-methylbutyl β-D-glucopyranoside, 3-methyl-2-butenyl β-Dglucopyranoside, geranyl β-D-glucopyranoside, perilloside A, and cyclohexyl β-D-glucopyranoside was accomplished in moderate yields by transglucosylation using hyperthermostable Pyrococcus furiosus β-glucosidase immobilized onto gelatin gel. Recovered immobilisate was reusable on successive runs in transglucosylation.
