- PROCESS FOR PREPARATION OF ALDONIC ACIDS AND DERIVATIVES THEREOF
-
A process for the preparation of L-gluconic acid or a salt thereof, comprises treating an aqueous solution of 6-bromo-6-deoxy-2,3-anhydro-D-manno-1,4-lactone with a base at a pH of at least 12 and at a temperature of 45 to 55° C. to obtain an aqueous solution of L-gluconic acid.

- L-Glucose. A convenient synthesis from D-glucose
-
L-Glucose has been synthesized from D-glucose by a convenient method involving methyl 2,3-O-isopropylidene-β-D-gulofuranosiduronic acid (6) as a key intermediate.Compound 6 was converted into L-glucono-1,5-lactone (8), which, by a selective reduction, afforded L-glucose (9).
