Convenient synthesis of -O-(6'-O-acyl-beta-D-galactopyranosyl)-sn-glyc
erol was studied. The lipase from Achromobacter sp, catalyzed acylatio
n of 3-O-beta-D-galactopyranosyl-sn-glycerol, which contains two prima
ry hydroxyl functions, proceeded regioselectively to furnish 1-O-acyl-
3-O-beta-D-galactopyranosyl-sn-glycerol.
