the deacylation of 4-C-acyloxymethyl-3,5-di-O-acyl-1,2-O-(1-methylethylidene)-beta-L-threo-pentofura nose to form 3,5-di-O-acyl-4-C-hydroxymethyl-1,2-O-(1-methylethylidene)-alpha-D-xylo-pentofura nose in a highly selective and efficient manner. The rate of lipase-catalyzeddeacylation of tributanoyl furanose is 2.3 times faster than the rate of deacylation of the triacetyl furanosederivative. In order
