Abstract: Efficient regio- and stereoselective deacylation of acyloxy function involving C-5′ hydroxyl group of -anomer over the other similar C-5′ acyl group of -anomer and acyl groups involving secondary hydroxyls in anomeric mixture of peracylates of D-ribose has been achieved during deacylation reaction mediated by Lipozyme® TL IM (Thermomyces lanuginosus lipase immobilized on silica). This enzymatic methodology has been efficiently used for the separation of anomeric mixtures of peracylated ,-D-ribofuranosides.
