Enzymatic Synthesis of ω-Hydroxyalkyl and n-Alkyl β-D-Galactopyranosides by the Transglycosylation Reaction of β-Galactosidase

Abstract ω-Hydroxyalkyl and n-alkyl β-D-galactopyranosides were directly prepared in high yield from 1,8-octanediol, 1,10-decanediol, 1-octanol and 1-decanol by the transglycosylation reaction of o-nitrophenyl β-D-galactopyranoside (ONPG) or lactose using β-galactosidase.
