Condensation reaction between lactose and glycerol was effectively catalyzed by utilizing a commercially available cellulase preparation from Trichoderma reesei. The enzyme induced the formation of 1-O-β-lactosyl-(R,S)-glycerol (1) and 2-O-β-lactosyl glycerol (2) in a molar ratio of 7:3 and in a 20% yield based on lactose added. The enzyme also induced the condensation of lactose with 1,3-propanediol to produce O-β-lactosyl propanediol (3) in a yield of 15%. When various alkanols (n: 2–8) and allyl alcohol were used in the condensation reaction, the corresponding alkyl and allyl β-lactoside were obtained in the yields of 0.9–3.8% of the desired compounds.
