The synthesis of some 7,7-difluoro-7,8-dihydropterins and pterins with fluoroalkyl subsitutents at the 6 or 7 positions from fluorine-containingaliphatic precursors and suitably substituted pyrimidines is described. The fluorine-containing pterins were found to be very insoluble and also stable to nucleophiles and bases in dilute aqueous solution.
