**A new, regiospecific synthesis of L‐biopterine** Pure L‐biopterine (I) is obtained in 35–40% yield by condensation of 5‐desoxy‐L‐arabinose‐hydrazone acetate with 2,4,5‐triamino‐6‐hydroxy‐pyrimidine, followed by oxidation of the formed tetrahydro‐derivative and deacetylation of the L‐bioterine dia

Abstract
– Die Kondensation von D, L‐2,3‐O‐Isopropyliden‐4‐methyl‐erythrulose mit 2,4,5‐Triamino‐6‐hydroxypyrimidin wird beschrieben. Die Luft‐Oxydation des hydrierten Kondensationsproduktes führt zu D, L‐1′,2′‐O‐Isopropyliden‐biopterin ohne Abspaltung der Seitenkette. Durch hydrolytische Abspaltung der Isopropylidengruppe wird in guter Ausbeute reines, isomerenfreies D, L‐Biopterin erhalten.
