Abstract

A facile method for enzymatic glycosylation of 4-substituted benzyl alcohols and tyrosol with glucose in a monophasic aqueous-dioxane medium was reported, using a crude meal of apple seed as a new catalyst. The corresponding β-d-glucosides were synthesized in moderate yields (13.1–23.1%), among which the salidroside was obtained in 15.8% yield.
