The application of Lipase enzymes to effect regioselective C-3-O-acylation of - and -galactopyranosides displaying a range of anomeric substituents, and C-2-O-acylation of phenyl and ethyl is reported. In particular this method has allowed introduction of a variety of acyl protecting groups at the C-3 hydroxyl group of ethyl 11.
