• Simple syntheses of biopterin (<B>4a</B>) and its three optical isomers (<B>4b</B>, <B>c</B>, <B>d</B>) are described. The condensation of 2,4,5-triaminopyrimidin-6(1<I>H</I>)-one (<B>1</B>) with each of the 5-deoxypentose phenylhydrazones (<B>2a</B>, <B>b</B>, <B>c</B>, <B>d</B>), followed by oxidation with K<SUB>3</SUB>[Fe(CN)<SUB>6</SUB>] and H<SUB>2</SUB>O<SUB>2</SUB> in the presence of KI, gives biopterin (<B>4a</B>) and the isomers (<B>4b</B>, <B>c</B>, <B>d</B>) respectively.
