Versuchsvorschrift

A more direct way to synthesise 3,4-dihydroxy-2-hydroxymethylpyrrolidine, D-tartrate is by reduring 2,3,5-Tri-O-benzyl-1,4-dideoxy-1,4-imino-D-arabinitol with Pd/C in glacial acetic acid. The formed, oily (2R,3R,4R)-3,4-dihydroxy-2-hydroxymethyl-pyrrolidine,acetate is dissolved in methanol and added to a solution containing D-tartraric acid at reflux and (2R,3R,4R)-3,4-dihydroxy-2-hydroxymethylpyrrolidine, D-tartrate is formed and can be isolated by filtration. Ion exchange chromatography is thereby avoided.
