Maximum separation of xylose from furfural and acetic acid was achieved when the treated membranes had A values of 5 5-7 L m(-2) h(-1) bar(-1) Using an optimized membrane with A value of approximately 6 L m(-2) h(-1) bar(-1) a liquid fraction from hydrothermally pretreated rice straw was concentrated in a one-step FO process to increase sugar concentrations and decrease fermentation

Starting from furfural 1 an enantiopure bicyclic enone 5 having a bicyclo[3 2 1]octane framework was first prepared by employing either a lipase-mediated kinetic resolution procedure or a Sharpless asymmetric dihydroxylation procedure Thus in the enzymatic procedure furfural 1 was first transformed into the racemic enone ()-5 by employing the Achmatowicz rearrangement via the racemic
