Synthesis of Tetrahydropteridine C6-Stereoisomers, Including N5-Formyl-(6S)-tetrahydrofolic Acid

Chiral N1-protected vicinal diamines derived from amino acids were condensed with 2-amino-6-chloro-5-nitro-4(3H)-pyrimidinone, the nitro group reduced, and the amine deprotected.Oxidative cyclization of the resulting triaminopyrimidinone via quinoid pyrimidine intermediates gave a quinoid dihydropteridine, which was then reduced to a tetrahydropteridine C6-stereoisomer.Thus, 6(R)- and 6(S)-propyltetrahydropterin were stereospecifically synthesized (99 percent enantiomeric purity) in good yield from D- and L-norvaline, respectively.Reductive alkylation of (p-aminobenzoyl)-L-glutamate with a niropyrimidine aldehyde derived from D- or L-serine similarly afforded, after cyclization and reduction, (6R)- or (6S)-tetrahydrofolic acid.The latter was then converted to the natural isomer of leucovorin by regioselective N5-formylation with carbonyl diimidazole / formic acid without loss of enantiomeric purity.
